[SCSI] lpfc 8.3.17: SCSI fixes

- Fail I/Os with incomplete data that complete with SCSI Check condition. - Complete aborted I/Os with host_scribble equal to NULL with success. - Initialize context1 field of iocbq in the new_scsi_buf routines. Signed-off-by: Alex Iannicelli <alex.iannicelli@emulex.com> Signed-off-by: James Smart <james.smart@emulex.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
