P2P: Fix ignoring of PD Response due to dialog token mismatch 

Commit 6b56cc2d97 added clearing of the
p2p->pending_action_state too early in this function. This should not
be done if we are going to silently ignore the frame due to dialog
token mismatch. Fix this by moving the code around to check the dialog
token first.

This issue resulted in PD Request retries getting stopped too early if
the peer is sending out an unexpected PD Response (e.g., because of it
being excessively slow with the response so that the response is
received only after the next TX attempt with a new dialog token).
