free_xs must be called at splbio().  This is usually the case since the main
caller is scsi_done which the controller interrupt handlers call.  In the
case of a non-buffer based transaction, the xs structure is freed by the
process that initiated the transfer in scsi_scsi_cmd.  In this case, an
explicit splbio/splx pair around the call to free_xs is required.  Without
the splbio protection, the xs free list could be corrupted, and the type
driver's start routine might run without spl protection.
