namespaces, pid_ns: fix leakage on fork() failure
BugLink: http://bugs.launchpad.net/bugs/1002880
commit 5e2bf0142231194d36fdc9596b36a261ed2b9fe7 upstream.
Fork() failure post namespace creation for a child cloned with
CLONE_NEWPID leaks pid_namespace/mnt_cache due to proc being mounted
during creation, but not unmounted during cleanup. Call
pid_ns_release_proc() during cleanup.
