blkid: stop scanning on I/O error
Whenever we fail to read from a device it's pointless to
continue with probing; we should be failing immediately.
Otherwise the system will continue logging I/O errors.
This patch updates the probe functions to return the
negative error number on error and BLKID_PROBE_NONE
if not found.
