These allocations are sometimes done under a spin lock so they
have to be atomic. The function call tree is:
-> update_beacon() <- takes a spin lock
-> update_BCNTIM()
-> set_tx_beacon_cmd()

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.

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.
