mac80211: disable BSS color collision detection in case of no free colors
AP may run out of BSS color after color collision
detection event from driver.
Disable BSS color collision detection if no free colors are
available based on bss color disabled bit sent as a part of
NL80211_ATTR_HE_BSS_COLOR attribute sent in
NL80211_CMD_SET_BEACON.
It can be reenabled once new color is available.
