ath10k: Remove dedicated p2p_device interface capability for wcn3990

p2p_find uses primary interface mac address during active
scan instead of the later created p2p interface on which
wpa_supplicant is running.

wpa_supplicant creates a p2p_device interface if the driver
exposes a dedicated p2p_device interface capability. The mac
address for the created p2p_device interface will be same as of
the primary interface registered with the netdev.

By disabling the dedicated p2p_device interface capabilty
for wcn3990, wpa_supplicant uses the interface passed to it
from commandline interface and hence will use the correct
mac address for the active scan purpose.
