In doing my fsstress+EIO stress testing I started running into issues where umount would get stuck forever because the uuid checker was chewing through the thousands of subvolumes I had created. We shouldn't block umount on this, simply bail if we're unmounting the fs. We need to make sure we don't mark the UUID tree as ok, so we only set that bit if we made it through the whole rescan operation, but otherwise this is completely safe.
