dm thin: allow metadata commit if pool is in PM_OUT_OF_DATA_SPACE mode
commit 8d07e8a5f5bc7b90f755d9b427ea930024f4c986 upstream.
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.
