Fix remount when setting multiple properties. 

The previous code was checking zfs_is_namespace_prop() only for the
last property on the list.  If one was not "namespace", then remount
wasn't called.  To fix that move zfs_is_namespace_prop() inside the
loop and remount if at least one of properties was "namespace".
