commit e6d7eba23b666d85cacee0643be280d6ce1ebffc upstream.

Commit 4ab7bb976343 ("ata: libata-scsi: Refactor ata_scsiop_maint_in()")
modified ata_scsiop_maint_in() to directly call
ata_scsi_set_invalid_field() to set the field pointer of the sense data
of a failed MAINTENANCE IN command. However, in the case of an invalid
command format, the sense data field incorrectly indicates byte 1 of
the CDB. Fix this to indicate byte 2 of the command.
