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. Signed-off-by: Jia-Ju Bai <baijiaju1990@gmail.com> Signed-off-by: Martin K. Petersen <martin.petersen@oracle.com>
