[SCSI] libsas: Handle SCSI commands that complete with failure codes
This patch moves the code that handles SAS failures out of the main EH
function and into a separate function. It also detects commands that have
no sas_task (i.e. they completed, but with error data) and sends them into
scsi_error for processing. This allows us to handle SCSI errors (and
enables auto-spinup as a side effect) instead of dropping them on the
floor and falling into an infinite loop. It also requires the
implementation of a device reset function, which the SAS failure code has
been modified to employ for REQ_DEVICE_RESET.
