The index for r8188eu's vendor-specific control requests is not used.
Remove the index parameter from usbctrl_vendorreq and pass index 0 to
usb_control_msg.
This patch is an adaptation of commit 3d0be94f62fd ("staging: rtl8188eu:
ctrl vendor req index is not used") for the new r8188eu driver.

At the moment, usbctrl_vendorreq's requesttype parameter must be set to
1 for reading and 0 for writing. It's then converted to the actual
bmRequestType for the USB control request. We can simplify the code and
avoid this conversion if the caller passes the actual bmRequestType.
This patch is an adaptation of commit 788fde031027 ("staging: rtl8188eu:
use actual request type as parameter") for the new r8188eu driver.

There are only two definitions from ethernet.h used in the driver.
Namely:
Both are only used in the file core/rtw_recv.c. Replace the usage of
ETHERNET_HEADER_SIZE with ETH_HLEN, move the definition of LLC_HEADER_SIZE
into rtw_recv.h and remove the now unused ethernet.h header file.

The struct ip_options declared in ip.h is only unsed in the optlength
macro which is also defined in ip.h and not used in the driver code.
All other definitions/declarations in ip.h are duplicated from
<include/uapi/linux/ip.h>. Remove the ip.h header file and its includes.

Many defined constants in wifi.h are unused and/or available from
<linux/ieee80211.h>, some with slightly different names. Remove
the constants from ieee80211.h and wifi.h and use the common ones. Rename where
necessary.
The bRequest value for the vendor specific control requests sent by this
driver is always 0x05. Replace the function parameter with the define from
usb_ops.h.
This patch is an adaptation of commit eeb4661560ff ("staging: rtl8188eu:
ctrl vendor req value is always 0x05") for the new r8188eu driver.

Remove the function _rtw_zvmalloc from os_dep/osdep_service.c, as this
function is now unused and is just an inline wrapper around vmalloc
which zeroes out the memory. All previous callers have been converted to
use vzalloc. Also remove the declaration from include/osdep_service.h.
It is considered generally bad practice to declare functions as inline in
the majority of cases, as not only can this qualifier be ignored by the
compiler but the compiler generally makes good decisions about inlining
anyway.

Remove the function _rtw_vmalloc from os_dep/osdep_service.c, converting
its only user (also in os_dep/osdep_service.c) to use plain vmalloc.
This function is just an inline wrapper around vmalloc which returns a u8
pointer, which isn't needed. Also remove the declaration from
include/osdep_service.h.
