scsi: message: fusion: Replace GFP_ATOMIC with GFP_KERNEL
mpt_attach() and mptfc_probe() are never called in atomic context. They
call kzalloc() and kcalloc() with GFP_ATOMIC, which is not necessary.
GFP_ATOMIC can be replaced with GFP_KERNEL.
This is found by a static analysis tool named DCNS written by myself.
