Hauke Mehrtens a9363914a3 mac80211: Allow IBSS mode and different beacon intervals
ath10k-ct supports the combination to select IBSS (ADHOC) mode and
different beacon intervals together. mac80211 does not like this
combination, but Ben says this is ok, so remove this check.

ath10k-ct starting with version 5.2 allows the combination of
NL80211_IFTYPE_ADHOC and beacon_int_min_gcd in ath10k_10x_ct_if_comb
which triggers this warning. Ben told me that this is not a big problem
and we should ignore this.
