[PATCH] wifi: mac80211_hwsim: set link ID information during Rx

[Aditya Kumar Singh]

Currently link ID information is not passed to mac80211 via Rx status by
mac80211_hwsim. This leads to packet getting dropped in function
__ieee80211_rx_handle_packet since it expects the link ID if packet is
intended for a MLO station and the station is not directly passed via
pubsta function argument.

Add changes to pass the link ID information in Rx status.
