Log Message:
refactor ata_xfer to be just dumb structure; move all callouts/condvars out

retry callout to wd(4); reset callout and the active/cmd finish condvars
to channel queue; change code using the condvars so it works if there
are multiple waiters

simplify the async wait code for cmds, replace ata_wait_xfer()/ata_wake_xfer()
with ata_wait_cmd()

fix the callout_invoking/ack race handling code for timeouts to
actually have chance to work; change mvsata(4) to use generic timeout func

towards resolution of kern/52614
