scsi: core: scsi_error: Do not queue pointless abort workqueue functions

If a host template doesn't implement the .eh_abort_handler() there is no
point in queueing the abort workqueue function; all it does is invoking
SCSI EH anyway.  So return 'FAILED' from scsi_abort_command() if the
.eh_abort_handler() is not implemented and save us from having to wait for
the abort workqueue function to complete.
