[PATCH 7/8] rrm: React to IFTYPE_CHANGE events

[Denis Kenzior <denkenz@gmail.com>]

[-- Attachment #1: Type: text/plain, Size: 884 bytes --]

If a netdev iftype is changed, all frame registrations are removed.
Make sure to re-register for the appropriate frame notifications in case
our iftype is switched back to 'station'.  In any other iftype, no frame
watches are registered and rrm_state object is effectively dormant.
