dm thin: allow metadata commit if pool is in PM_OUT_OF_DATA_SPACE mode
Commit 3e1a0699 ("dm thin: fix out of data space handling") introduced a regression in the metadata commit() method by returning an error if the pool is in PM_OUT_OF_DATA_SPACE mode. This oversight caused a thin device to return errors even if the default queue_if_no_space ENOSPC handling mode is used. Fix commit() to only fail if pool is in PM_READ_ONLY or PM_FAIL mode.
