[SCSI] libfc: Move host_lock usage into ramp_up/down routines
[SCSI] libfc: Move host_lock usage into ramp_up/down routines

The host_lock is still used to protect the can_queue
value in the Scsi_Host, but it doesn't need to be held
and released by each caller. This patch moves the lock
usage into the fc_fcp_can_queue_ramp_up and
fc_fcp_can_queue_ramp_down routines.
