While testing latest updates I hit lockdep warning:

[ 42.695120] 5.14.0+ #25 Tainted: G C
[ 42.695422] --------------------------------------------
[ 42.695747] RTW_CMD_THREAD/317 is trying to acquire lock:

[ 42.697758]
[ 42.697758] other info that might help us debug this:

[ 42.698847] ----

[ 42.699418]
[ 42.699418] *** DEADLOCK ***
[ 42.699418]
[ 42.699768] May be due to missing lock nesting notation
It's false positive, since all queue spinlocks are initialized via
private API which has pqueue as agrument. Fix it by making
_rtw_init_queue a macro instead of function + removed unneeded _ prefix.
