The hisi_sas_slot.is_internal member is not set properly for ATA commands
which the driver sends directly. A TMF struct pointer is normally used as
a test to set this, but it is NULL for those commands. It's not ideal, but
pass an empty TMF struct to set that member properly.

Fixes: dc313f6b125b ("scsi: hisi_sas: Factor out task prep and delivery code")

Please consider this change for v5.17, thanks!
