wifi: iwlwifi: mvm: include link ID when releasing frames
[ Upstream commit e78d7877308989ef91b64a3c746ae31324c07caa ]
When releasing frames from the reorder buffer, the link ID was not
included in the RX status information. This subsequently led mac80211 to
drop the frame. Change it so that the link information is set
immediately when possible so that it doesn't not need to be filled in
anymore when submitting the frame to mac80211.
