P2P: Fix p2p_ignore_shared_freq=1 during invitation processing

Browse source 
p2p_ignore_shared_freq=1 was supposed to allow a MCC-capable device to
ignore a preference for using the same channel on multiple interfaces.
However, it was not used during processing of an Invitation Request. Fix
that case to use channel preference instead of channel forcing if free
channels are available. This allows p2p_ignore_shared_freq=1 case to
ignore the preference.
