d4359923e1 Fix DHCP/NDISC snoop deinit followed by failing re-init
It was possible to hit a double-free on the l2_packet socket if
initialization of DHCP/NDISC snoop failed on a hostapd interface that
had previously had those enabled successfully. Fix this by clearing the
l2_packet pointers during deinit.

For example:

All environments of the current frequency band and country (default)

Outdoor environment only
country3=0x4f

Indoor environment only
country3=0x49

Noncountry entity (country_code=XX)

Commit 01e2231fdc ('hostapd: Skip some

hapd->iface->mconf being NULL. This was within #ifdef CONFIG_MESH, so it
should not impact hostapd, but it can impact AP mode with

conditional on hapd->conf->mesh being enabled.

79329ae0aa P2P: Verify local driver preferred frequencies for P2P use cases
Previously the peer operating channel preference was accepted if the
indicated frequency was listed in the local preference list from the
driver. This was assuming that the driver included only channels that
are currently enabled for GO operation. Since that might not be the
case, filter the local preference list by doing an explicit validation
of the indicated channels for P2P support.

This moves the similar validation steps from two other code paths in
p2p_check_pref_chan_recv() and p2p_check_pref_chan_no_recv() into a
common filtering step in p2p_check_pref_chan() for all three cases.

This avoids issues to start the GO in cases where the preferred
frequency list from the driver may include channels that are not
currently enabled for P2P GO use (e.g., 5 GHz band in world roaming
configuration).
