[PATCH wireless-next] wifi: mac80211: set default WMM parameters on all links

From: Ramanathan Choodamani <quic_rchoodam at quicinc.com>

Currently, mac80211 only initializes default WMM parameters
on the deflink during do_open(). For MLO cases, this
leaves the additional links without proper WMM defaults
if hostapd does not supply per-link WMM parameters, leading
to inconsistent QoS behavior across links.

Set default WMM parameters for each link during
ieee80211_vif_update_links(), because this ensures all
individual links in an MLD have valid WMM settings during
bring-up and behave consistently across different BSS.
