Denis V. Lunev 5d1e4468a7 [NETNS]: Make netns refconting debug like a socket one. ...

Make release_net/hold_net noop for performance-hungry people. This is a debug
staff and should be used in the debug mode only.

Add check for net != NULL in hold/release calls. This will be required
later on.

[ Added minor simplifications suggested by Brian Haley. -DaveM ]
