Drivers using libsas have to issue their own TMFs, and the code to do this is duplicated between drivers. Add a common function to handle TMFs. This will be also used for sending ATA commands, but use name "tmf" as the purpose is similar between SCSI and ATA in the usage. The force_phy_id argument will be used for a hisi_sas HW bug workaround. We check the sas task status stat field against TMF codes, as according to the SAS v1.1 spec 9.2.2.5.3, if response_data is in datapres, then the response code should be a TMF code - see table 128.

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).

LLDD TMF callbacks may return linux or other error codes instead of TMF codes. This may cause problems in sas_scsi_find_task() -> .lldd_query_task(), as only TMF codes are handled there. As such, we may not return a task_disposition type from sas_scsi_find_task(). Function sas_eh_handle_sas_errors() only handles that type, and will only progress error handling for those recognised types. Return TASK_ABORT_FAILED upon exit on the assumption that the command may still be alive and error handling should be escalated.
