staging: rtl8188eu: use GFP_ATOMIC under spinlock
We're holding a spinlock here so we can't do sleeping allocations.
The call tree is:
rtw_sta_flush() <-- takes spin_lock_bh(&pstapriv->asoc_list_lock);
--> ap_free_sta()
--> rtw_clearstakey_cmd()
Originally these calls were rtw_zmalloc() and then we switched them to
kzalloc() in fadbe0cd52
('staging: rtl8188eu:Remove rtw_zmalloc(),
wrapper for kzalloc()') and that made the bugs show up for my static
checker. The original code was buggy as well but my static checker
couldn't parse it.
