scsi: lpfc: Fix missing MDS functionality

Visual code inspection of the MDS implementation revealed two errors in
the driver:

 - The set features Feature Code had an incorrect value

 - The routine that classifies command type for cmd completions was missing
   the Send Frame definition. Send Frame is used for MDS driver loopback.
