cfg80211: remove @gfp parameter from cfg80211_rx_mgmt()
In the cfg80211_rx_mgmt(), parameter @gfp was used for the memory allocation.
But, memory get allocated under spin_lock_bh(), this implies atomic context.
So, one can't use GFP_KERNEL, only variants with no __GFP_WAIT. Actually, in all
occurrences GFP_ATOMIC is used (wil6210 use GFP_KERNEL by mistake),
and it should be this way or warning triggered in the memory allocation code.
Remove @gfp parameter as no actual choice exist, and use hard coded
GFP_ATOMIC for memory allocation.
