 Log Message:
 adjust reset channel and dump paths
 - channel reset now always kills active transfer, even on dump path, but
   now doesn't touch the queued waiting transfers; also kill_xfer hook is
   always called, so that HBA can free any private xfer resources and thus
   the dump request has chance to work
 - kill_xfer routines now always call ata_deactivate_xfer(); added KASSERT()s
   to ata_free_xfer() to expect deactivated xfer
 - when called during channel reset before dump, ata_kill_active() drops
   any queued waiting transfers without processing
 - do not (re)queue any transfers in wddone() when dumping
 - kill AT_RST_NOCMD flag
 
 This should also hopefully fix the 'polled command has been queued' panic

 dump tested working with piixide(4) and ahci(4). mvsata(4) dump times out,
 but otherwise tested working, will be fixed separately. siisata(4) mechanically
 changed and not tested.
