bab6677a31 Handle Wi-Fi Display commands more carefully if P2P is disabled
If P2P was disabled (e.g., due to driver not supporting it or through
p2p_disabled=1 configuration), setting Wi-Fi Display parameters could
result in segmentation fault when the WFD IE is updated without the P2P
module being initialized. Fix this by skipping the update if P2P module
is not in use. In addition, show Wi-Fi Display as disabled in "GET
wifi_display" and refuse to enable it with "SET wifi_display 1" if P2P
is not enabled.

9675ce354a WFD: Add Wi-Fi Display support
This commit adds control interface commands and internal storage of
Wi-Fi Display related configuration. In addition, WFD IE is now added
to various P2P frames, Probe Request/Response, and (Re)Association
Request/Response frames. WFD subelements from peers are stored in the
P2P peer table.

Following control interface commands are now available:
SET wifi_display <0/1>
GET wifi_display
WFD_SUBELEM_SET <subelem> [hexdump of length+body]
WFD_SUBELEM_GET <subelem>
