[PATCH BlueZ 12/12] mesh: Switch beaconing net key

[Brian Gix <brian.gix@gmail.com>]

From: Brian Gix <brian.gix@intel.com>

When transitioning from Phase 1 to Phase 2 of a network key and we are
beaconing, we need to halt the beaconing on the old key version, and
begin beaconing on the new key version.
