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.
