Register .sync_fs handler

Browse Source 
Register the missing .sync_fs handler.  This is a noop in most cases
because the usual requirement is that sync just be initiated.  As part
of the DMU's normal transaction processing txgs will be frequently
synced.  However, when the 'wait' flag is set the requirement is that
.sync_fs must not return until the data is safe on disk.  With the
addition of the .sync_fs handler this is now properly implemented.
