Several tests do not pass due to some additional changes that have
not been merged. Remove these cases and add some hardening after
discovering some unfortunate wpa_supplicant behavior.
- Disable p2p in wpa_supplicant. With p2p enabled an extra device
is created which starts receiving DPP frames and printing
confusing messages.
- Remove extra asserts which don't make sense currently. These
will be added back later as future additions to PKEX are
upstreamed.
- Work around wpa_supplicant retransmit limitation. This is
described in detail in the comment in pkex_test.py
update_config=1 lets wpa_supplicant write config changes
to the config file. In the real world this is what you want
so your DPP credentials are persistant. But for testing this
is not correct since multiple tests use the same config file
and expect it to be pristine.
Occationally wpa_supplicant was connecting to the AP without
running DPP because the config already had the network
credentials.
