Can these be reached in practice? Shouldn't such cases be prevented from
starting AP operation?

No "return;" at the end of void function.

Please do not include unrelated (and in this case, an undesired
whitespace change in general) changes in the patch.

Why is that mbssid_count added here? It does not seem to be used in any
of the following patches.. Or well, it is just used to check whether
MBSSID mechanism is to be enabled and a single bool would seem to be a
clearer way of indicating that to cover the case of mbssid_index == 0.
Or well, I guess even that bool would be unnecessary since
mbssid_tx_iface != NULL would indicate if this is enabled for both the
transmitting BSSID and the nontransmitting ones.
