hostap: Remove in_atomic() check.

Browse source 
hostap_get_wireless_stats() is the iw_handler_if::get_wireless_stats()
callback of this driver. This callback was not allowed to sleep until
commit a160ee69c6 ("wext: let get_wireless_stats() sleep") in v2.6.32.

Remove the therefore pointless in_atomic() check.
