AHCI - properly initialize ccb_xa.flags in softreset, make poll code robust
* The softreset code did not properly initialize ccb_xa.flags, causing
the softreset FIS's to sometimes get queued as an NCQ command instead of
as a non-NCQ command.
* Make ahci_poll() a bit more robust. Properly set ccb_xa.state on
timeout, check for unexpected completions, and check to see if the
ccb was put on a queue (though the latter should never happen since
active/sactive is cleared by ahci_get_err_ccb()).
