From: Miklos Szeredi <miklos@szeredi.hu>
This patch sets ->mnt_namespace where it's actually added to the
namespace.
Previously mnt_namespace was set in do_kern_mount() even if the filesystem
was never added to any process's namespace (most kernel-internal
filesystems).
This discrepancy doesn't actually cause any problems, but it's cleaner if
mnt_namespace is NULL for these non exported filesystems.
