P2P: Fix remain-on-channel use with PD/Invitation Request while in Listen
If Listen state was in progress on another channel when a request to
send an Action frame (e.g., Provision Discovery Request or Invitation
Request to a peer on the peer's Listen channel that is different from
our Listenc hannel) is issued, wpa_supplicant tried to use concurrent
remain-on-channel operations. While some drivers can handle this
cleanly, there are drivers that don't and wpa_supplicant is not expected
to request concurrent remain-on-channel operations.
Fix this by cancelling the ongoing remain-on-channel with stop_listen
prior to sending the Action frame on another channel. If a P2P search
was in progress, it will be continued after the timeout on the new
operation.
