[RFC PATCH 3/4] wifi: rtw89: handle P2P_DEVICE in net_type/self_role switch

rtw89_vif_type_mapping() has a second switch (vif->type) beyond the
wifi_role mapping already fixed -- this one sets net_type/self_role
and also ends in a default: WARN_ON(1). Live-tested on real hardware
(RTL8922AE): the moment wpa_supplicant/NetworkManager requested a
P2P-Device wdev (NL80211_CMD_START_P2P_DEVICE), this WARN_ON fired
immediately, confirmed via the exact call chain this project's
BUILD_LOG.md had already traced by hand: nl80211_start_p2p_device ->
ieee80211_start_p2p_device -> ieee80211_do_open -> drv_add_interface ->
rtw89_ops_add_interface -> __rtw89_ops_add_iface_link ->
rtw89_vif_type_mapping.

This second switch was present in the original research grep
(core.c:5702, two switch(vif->type) sites found) but was not actually
read/analyzed at the time -- a real gap in that research pass, caught
by this live test rather than by review.

Add NL80211_IFTYPE_P2P_DEVICE alongside the existing MONITOR case,
which also just breaks without setting net_type/self_role: a
P2P-Device interface has no BSS/association state, so leaving these at
their zero-initialized defaults (RTW89_NET_TYPE_NO_LINK,
RTW89_SELF_ROLE_CLIENT) is correct, same reasoning already applied to
MONITOR.

Verified live: after this fix, wpa_supplicant successfully created a
real P2P-Device wdev (confirmed via `iw dev`: phy#1 now lists a
non-netdev interface, type P2P-device, alongside wlan0), with zero
WARN/BUG in dmesg for the whole boot, and normal STA association/
roaming continuing to work correctly (multiple successful associate/
reassociate cycles observed with this driver loaded).
