wifi: mac80211: set info->band for 802.3 encap offload frames
Unlike the 802.11 TX paths, ieee80211_8023_xmit() does not set
info->band from the channel context on non-MLD interfaces. It stays at
0, so ieee80211_get_tx_rates() uses the wrong band for these frames.
Set it the same way as ieee80211_build_hdr(): drop the frame if there is
no channel context, and leave the band at 0 on MLD interfaces.
