P2P: Fix PD retries on delay in off channel transmission

Browse Source 
Commit 488f4a7108 configures a timer
before p2p_send_action(). This may result in the timer getting fired
earlier to the off channel transmission of the frame and thus another PD
request being retransmitted. This shall lead to the new PD request with
an incremented dialog token being transmitted. For the cases where the
later PD request might not be transmitted as the host driver is busy
transmitting the earlier frame, the received PD response could be
dropped for the dialog token mismatch. Remove the timer configuration to
avoid this behavior.
