[PATCH] drivers/fsi: sbefifo: fix call_kern.cocci warnings

[Julia Lawall <julia.lawall@lip6.fr>]

Function sbefifo_enq_xfr called inside lock from sbefifo_write_common but
uses GFP_KERNEL.  Change to GFP_ATOMIC.

Generated by: scripts/coccinelle/locks/call_kern.cocci

Semantic patch information:
 The proposed change of converting the GFP_KERNEL is not necessarily the
 correct one.  It may be desired to unlock the lock, or to not call the
 function under the lock in the first place.
