mesh: Fix VHT Operation information in peering messages

The full VHT channel information was not set in the hostapd data
structures which resulted in incorrect information (all zeros) being
used when building the VHT Operation element for peering messages while
the actual driver mode was set with the full details. We did not seem to
use the VHT information from peering messages, so this does not change
behavior with another wpa_supplicant-based mesh implementation. Anyway,
these elements should match the ones used in Beacon frames.
