bfa: allocate memory with GFP_ATOMIC in spinlock context
bfa_fcb_pbc_vport_create() is called only from bfa_fcs_pbc_vport_init(),
that is called only from bfad_drv_start() with bfad_lock spinlock held.
So the patch replaces GFP_KERNEL with GFP_ATOMIC to avoid
sleeping in atomic spinlock context.
Found by Linux Driver Verification project (linuxtesting.org).
