scsi: hisi_sas: Include TMF elements in struct hisi_sas_slot

Browse Source 
In future scenarios we will want to use the TMF struct for more task types
than SSP.

As such, we can add struct hisi_sas_tmf_task directly into struct
hisi_sas_slot, and this will mean we can remove the TMF parameters from the
task prep functions.
