FROMGIT: wifi: nl80211: send MLO links channel info in GET_INTERFACE

Browse Source 
Currently, MLO link level channel information not sent to
userspace when NL80211_CMD_GET_INTERFACE requested on MLD.

Add support to send channel information for all valid links
for NL80211_CMD_GET_INTERFACE request.
