[SCSI] mptfusion: move fc event/reset handling to mptfc
Move fibre channel event and reset handling to mptfc. This will result in fewer changes over time that need to be applied to either mptbase.c or mptscsih.c. Signed-off-by: Michael Reed <mdr@sgi.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
