cfg80211: initialize on-stack chandefs
In a few places we don't properly initialize on-stack chandefs, resulting in EDMG data to be non-zero, which broke things. Additionally, in a few places we rely on the driver to init the data completely, but perhaps we shouldn't as non-EDMG drivers may not initialize the EDMG data, also initialize it there.
