Implement asynchronous channel reset.
Use this to reset the channel before doing a dump, instead of the hack in
wdc_exec_xfer() based on C_POLL. This hack was causing problems on
controllers with a shared queue, because we now can have C_POLL set during
concurent channels probes (problem found and analysed on sparc64 by
Martin Husemann).
This should even make core dumps marginally more reliable on ATA drives.
