scsi: lpfc: Correct LCB ACCept payload
After memory allocation for the LCB response frame, the memory wasn't zero initialized, and not all fields are set. Thus garbage shows up in the payload. Fix by zeroing the memory at allocation. Also properly set the Capability field based on duration support.
