ata: sata_mv, avoid trigerrable BUG_ON
commit e9f691d899188679746eeb96e6cb520459eda9b4 upstream.
There are several reports that the BUG_ON on unsupported command in
mv_qc_prep can be triggered under some circumstances:
https://bugzilla.suse.com/show_bug.cgi?id=1110252
https://serverfault.com/questions/888897/raid-problems-after-power-outage
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1652185
https://bugs.centos.org/view.php?id=14998
Let sata_mv handle the failure gracefully: warn about that incl. the
failed command number and return an AC_ERR_INVALID error. We can do that
now thanks to the previous patch.
Remove also the long-standing FIXME.
[v2] use %.2x as commands are defined as hexa.
