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.

Convert the only call to rtw_vmalloc in os_dep/ioctl_linux.c to the
kernel's existing vmalloc function, as rtw_malloc is just a preprocessor
definition for _rtw_vmalloc. The _rtw_vmalloc function is defined inline
and returns a u8, wrapping standard vmalloc. This behaviour is not necessary.

The compiler is free to ignore, or follow, "inline" markings so they
really have no use in .c files, so just remove them.
This allows functions to properly show up as being unused when all
callers to them are removed, otherwise gcc does not warn you about this.

These changes are a backport of associated newer changes made in the v5.6.4.2
rtl8812au driver, and correct problems in the previous initialization process
that caused multiple kernel traps on startup.
The kernel module failed to build
on arm64 platform. Other platforms like x86 can build without problem
because the csum_ipv6_magic function are defined in arch specific
asm/checksum.h, which is missing on arm64 platform.

This version does not currently work on newer kernels, but it does
contain USB ID 2001:3319, which a lot of other repos in GitHub does not.
