mac80211: consider virtual mon when calculating min_def
When calculating the current max bw required for
a channel context, we didn't consider the virtual
monitor interface, resulting in its channel context
being narrower than configured.
This broke monitor mode with iwlmvm, which uses the
minimal width.
