[PATCH] nsproxy cloning error path fix

[Pavel <xemul@openvz.org>]

This patch fixes copy_namespaces()'s error path.

when new nsproxy (new_ns) is created pointers to namespaces (ipc, uts)
are copied from the old nsproxy. Later in copy_utsname, copy_ipcs, etc.
according namespaces are get-ed. On error path needed namespaces are
put-ed, so there's no need to put new nsproxy itelf as it woud cause
putting namespaces for the second time.

Found when incorporating namespaces into OpenVZ kernel.
