scsi: remove abuses of scsi_populate_tag
Unless we want to build a SPI tag message we should just check SCMD_TAGGED instead of reverse engineering a tag type through the use of scsi_populate_tag_msg. Also rename the function to spi_populate_tag_msg, make it behave like the other spi message helpers, and move it to the spi transport class.
