scsi: lpfc: Driver responds LS_RJT to Beacon Off ELS - Linux

Browse Source 
Beacon OFF from switch is rejected by driver.

Driver fails Beacon OFF if frequency is set to 0. As per fc-ls spec,
status, capability, frequency and duration fields are only applicable
for Beacon ON.

Remove frequency and type checks. Reject Beacon ON if duration is non
zero.
