[SCSI] mptfc: set fibre channel fw target missing timers to one second

Browse Source 
The fibre channel firmware provides a timer which is similar in purpose
to the fibre channel transport's device loss timer.  The effect of this
timer is to extend the total time that a target will be missing beyond
the value associated with the transport's timer.  This patch changes
the firmware timer to a default of one second which significantly reduces
the lag between when a target goes missing and the notification of the
fibre channel transport.
