Tom Caputi 0b606cb33f Fix ztest deadlock in ztest_zil_remount()
This patch fixes a small race condition in ztest_zil_remount()
that could result in a deadlock. ztest_device_removal() calls
spa_vdev_remove() which may eventually call spa_reset_logs().
If ztest_zil_remount() attempts to call zil_close() while this
is happening, it may fail when it asserts !zilog_is_dirty(zilog).
This patch simply adds locking to correct the issue.
