Hu Wang 445dbe2cdb P2P: Do not stop Listen state if it is moving to correct channel
Commit 0b8889d8e5 ("P2P: Do not stop Listen state if it is on
correct channel") added a optimization to use Listen state's
remain-on-channel to send out GO Negotiation response frame quickly.

But in Listen state, if GO Negotiation request frame is received before
the remain-on-channel started event from the driver, the above
optimization is not triggered. This showed up in following manner in the
debug log:

p2p0: Starting radio work 'p2p-listen'@0xb4000070ae22d420 after 0.000114 second wait
nl80211: Remain-on-channel cookie 0x100 for freq=2412 MHz duration=204
P2P: Received GO Negotiation Request from 6e:fa:a7:86:e5:e5(freq=2412)
P2P: GO Negotiation with 6e:fa:a7:86:e5:e5
P2P: Stopping find
P2P: Clear timeout (state=WAIT_PEER_CONNECT)
P2P: State WAIT_PEER_CONNECT -> IDLE
nl80211: Cancel remain-on-channel with cookie 0x100
p2p0: Radio work 'p2p-listen'@0xb4000070ae22d420 done in 0.074348 seconds
p2p0: radio_work_free('p2p-listen'@0xb4000070ae22d420): num_active_works --> 0
P2P: State IDLE -> GO_NEG
P2P: Sending GO Negotiation Response
Off-channel: Send action frame: freq=2412 dst=6e:fa:a7:86:e5:e5 src=da:3c:83:7d:70:2b bssid=da:3c:83:7d:70:2b len=196
nl80211: Remain-on-channel event (cancel=0 freq=2412 channel_type=0 duration=400 cookie=0x100 (match))
nl80211: Remain-on-channel event (cancel=1 freq=2412 channel_type=0 duration=0 cookie=0x100 (match))
P2P: GO Negotiation Response (failure) TX callback: success=0

Fix this by adding p2p->pending_listen_freq == freq condition for the
optimization so that the case where the remain-on-channel command has
already been issued to the driver, but the start event has not yet been
received, is covered as well.

This package may include either wpa_supplicant, hostapd, or both. See
README file respective subdirectories (wpa_supplicant/README or
hostapd/README) for more details.

Source code files were moved around in v0.6.x releases and compared to
earlier releases, the programs are now built by first going to a
subdirectory (wpa_supplicant or hostapd) and creating build
configuration (.config) and running 'make' there (for Linux/BSD/cygwin
builds).
