Benjamin Marzinski 1f27197247 dm mpath: stop queueing IO when no valid paths exist ...

'queue_io' is set so that IO is queued while paths are being
initialized.  Clear queue_io in __choose_pgpath if there are no valid
paths, since there are obviously no paths that can be initialized.
Otherwise IOs to the device will back up.
