Dan Williams ae5fbae0cc [SCSI] libsas: fix usage of ata_tf_to_fis 
Since commit 110dd8f19d "[SCSI] libsas: fix scr_read/write users and
update the libata documentation" we have been passing pmp=1 and is_cmd=0
to ata_tf_to_fis().  Praveen reports that eSATA attached drives do not
discover correctly.  His investigation found that the BIOS was passing
pmp=0 while Linux was passing pmp=1 and failing to discover the drives.
Update libsas to follow the libata example of pulling the pmp setting
from the ata_link and correct is_cmd to be 1 since all tf's submitted
through ->qc_issue are commands.  Presumably libsas lldds do not care
about is_cmd as they have sideband mechanisms to perform link
management.
