P2P: Fix shared frequency preference for concurrent operations

P2P: Fix shared frequency preference for concurrent operations

Commit 50285f5ca8086cca45afa42cd23c3a3c1cd58f40 changed number of rules
in channel selection and among other things, it broke the design where
the currently used operating channel on a virtual interface that is
shared by the same radio is preferred to avoid costs related to
multi-channel concurrency. Fix this regression by making the P2P module
aware of the shared channel and using that preference as the highest
priority when re-selecting the channel during negotiation.
