[PATCH v2 3/4] SUNRPC: register service on creation in current network namespace

[Stanislav Kinsbursky <skinsbursky@parallels.com>]

Service, using rpcbind (Lockd, NFSd) are starting from userspace call and thus
we can use current network namespace.
There could be a problem with NFSd service, because it's creation can be called
through NFSd fs from different network namespace. But this is a part of "NFSd
per net ns" task and will be fixed in future.
