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.
