Jia-Ju Bai f2d81d0f03 rtl8188eu: Fix a possible sleep-in-atomic bug in rtw_disassoc_cmd 
[ Upstream commit 08880f8e08 ]

The driver may sleep under a spinlock, and the function call path is:
rtw_set_802_11_bssid(acquire the spinlock)
  rtw_disassoc_cmd
    kzalloc(GFP_KERNEL) --> may sleep

To fix it, GFP_KERNEL is replaced with GFP_ATOMIC.
This bug is found by my static analysis tool and my code review.
