mac80211: set basic-rate for mesh interfaces

Basic rates were not set for mesh-interfaces, resulting in the undesired
behavior where 11s frames might be sent with a rate which was not
configured.

Depending on the driver, the basic rate might also be used to determine
the beacon rate configured to the chip. One such example are MediaTek
MT7915 platforms.
