staging: r8188eu: Fix a couple scheduling in atomic bugs

Browse Source 
These allocations are sometimes done while holding a spin_lock so they
have to be atomic.  The call tree looks like this:

-> rtw_set_802_11_connect() <- takes a spin_lock
   -> rtw_do_join()
      -> rtw_sitesurvey_cmd()  <-- does a GFP_ATOMIC allocation
         -> p2p_ps_wk_cmd()
