[PATCH] scsi: match wait_for_completion_timeout return type

[Nicholas Mc Guire]

wait_for_completion_timeout returns unsigned long not int. As other
instances of wait_for_completion_timeout in fc_fcp.c use ticks_left
of appropriate type, this name is used here as well.

Patch was only compile tested with x86_64_defconfig + SCSI_LOWLEVEL=y
CONFIG_SCSI_FC_ATTRS=m, CONFIG_LIBFC=m

Patch is against 4.0-rc3 (localversion-next is -next-20150310)
