Fixes deadlock described in this bug:

Specific crash report here:

This bug is a false positive lockdep warning since gtp and smc use
completely different socket protocols.

Lockdep thinks that lock_sock() in smc will deadlock with gtp's
lock_sock() acquisition.

Adding lockdep annotations on smc socket creation prevents these false
positives.

Move lockdep annotation to separate function for readability.
