mac80211: do not enforce start_disabled=1 when staidx>0

Allow to override "start_disabled" to 0 even if there are station
interfaces present on the radio. If "start_disabled" is not explicitly
defined, the original behaviour of setting it to 1 is retained.
In other words, the existence of station interfaces now only controls
the default value of "start_disabled", but does not enforce it to 1.
