rescan-scsi-bus.sh: add option --no-lip-scan
lip is a FC operation and can be used to rescan device but it can not
specify the channel and target. So add a new option to scan FC hosts
according to the SCSI general interface in sysfs:
/sys/class/scsi_host/hostX/scan.
The default value of no_lip_scan is 0 which does not change the
default behavior.
