wifi: mac80211: set ieee80211_prep_tx_info::link_id upon Auth Rx

This will be used by the low level driver.
Note that link_id  will be 0 in case of a non-MLO authentication.
Also fix a call-site of mgd_prepare_tx() where the link_id was not
populated.

Update the documentation to reflect the current state
ieee80211_prep_tx_info::link_id is also available in mgd_complete_tx().
