SUNRPC: set per-net PipeFS superblock before notification
There can be a case, when on MOUNT event RPC client (after it's dentries were created) is not longer hold by anyone except notification callback. I.e. on release this client will be destoroyed. And it's dentries have to be destroyed as well. Which in turn requires per-net PipeFS superblock to be set.
