fuse: use ->reconfigure() instead of ->remount_fs()
s_op->remount_fs() is only called from legacy_reconfigure(), which is not
used after being converted to the new API.
Convert to using ->reconfigure(). This restores the previous behavior of
syncing the filesystem and rejecting MS_MANDLOCK on remount.
Fixes: c30da2e981a7 ("fuse: convert to use the new mount API")
