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.
