[PATCH] set mnt_namespace in the correct place

[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.
