Convert all rtw_zvmalloc calls within the driver to use the existing
kernel vzalloc function, which has the same semantics. Also rewrite the
two places where it is mentioned in comments to say vzalloc, and remove
the redundant cast to struct adapter * in ./os_dep/usb_intf.c as vzalloc
returns void *.
The reason for the conversion is that rtw_zvmalloc is just a
preprocessor definition for _rtw_zvmalloc which itself is just an inline
wrapper around vmalloc which then zeroes the memory out. As vzalloc does
the same thing via usage of __GFP_ZERO, this code is redundant and can
subsequently be removed.

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.
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.
