P2P: Fix provisioning info clearing after successful WPS step

Browse source 
Previously, this provisioning info was cleared using the P2P Interface
Address of the GO as the key. That did not always work in the case the
where we joined an already running group. This could result in the next
connection to that same GO skipping provision discovery. Fix this by
finding the peer entry based on its P2P Device Address instead of the
P2P Interface Address which may not always be set.
