Jouni Malinen c599ddd124 tests: Allow fallback to 20 MHz in ap_ht40_5ghz_invalid_pair
This test case for enforcing that AP setup fails in case there is need
to fall back to 20 MHz channel due to invalid 40 MHz configuration.
Modify this to allow successful AP startup as long as 40 MHz channel
does not get enabled.
