scsi: qla2xxx: Return ENOBUFS if sg_cnt is more than one for ELS cmds

commit ce2065c4cc4f05635413f63f6dc038d7d4842e31 upstream.

Firmware only supports single DSDs in ELS Pass-through IOCB (0x53h), sg cnt
is decided by the SCSI ML. User is not aware of the cause of an acutal
error.

Return the appropriate return code that will be decoded by API and
application and proper error message will be displayed to user.
