scsi: libsas: Add struct sas_tmf_task
Some of the LLDDs which use libsas have their own definition of a struct
to hold TMF info, so add a common struct for libsas.
Also add an interim force phy id field for hisi_sas driver, which will be
removed once the STP "TMF" code is factored out.
Even though some LLDDs (pm8001) use a u32 for the tag, u16 will be adequate,
as that named driver only uses tags in range [0, 1024).
