[RFC blktests v1 01/10] common/xfs: propagate errors from _xfs_run_fio_verify_io

[Daniel Wagner <dwagner@suse.de>]

If _xfs_mkfs_and_mount fails _xfs_run_fio_verify_io will continue to
execute and fio will run against the local file system instead against
the block device.

Propagate all errors back to the caller.
