So this is going the opposite direction of what I was thinking of, i.e.,
hardcoding NL80211_MESHCONF_RSSI_THRESHOLD to be set regardless of
whether this was configured in wpa_supplicant. Do we really want to do
this instead of leaving the kernel to use its default value if the new
mesh_rssi_threshold parameter is not explicitly set?
