George Amanakis 11943656f9 Update the MOS directory on spa_upgrade_errlog() 
spa_upgrade_errlog() does not update the MOS directory when the
head_errlog feature is enabled. In this case if spa_errlog_sync() is not
called, the MOS dir references the old errlog_last and errlog_sync
objects. Thus when doing a scrub a panic will occur:

Call Trace:

Fix this by updating the related MOS directory objects in
spa_upgrade_errlog().
