Align MSCS response handling as described in IEEE P802.11-REVme/D4.0,
11.25.3 (MSCS procedures):
If an MSCS Descriptor element is present in a MSCS Response
frame that does not indicate a status of "SUCCESS", the request
type field is set to "change" - the element indicates a suggested
set of parameters that could be accepted by the AP in response to a
subsequent request by the non-AP STA.
Handle both MSCS Response frame and (Re)Association Response frame with
change request by extending WPA_EVENT_MSCS_RESULT with the change
values.
Note: since we extend MSCS_RESULT event, move the original event from
both MSCS Response frame and (Re)Association Response frame handlers to
a common function that handles now both 'change' and other response.

cfg80211 requires the link ID to be specified for requests to start a
remain-on-channel operation during an ML association. This feels wrong
since the ROC operation is in most cases unrelated to the
association. However, that requirement has been in place since kernel
commit 7b0a0e3c3a88 ("wifi: cfg80211: do some rework towards MLO link
APIs") from April 2022, and as such, it looks necessary to have
wpa_supplicant work around this by specifying the currently used link ID
that would seem to match the ROC channel most closely.

The wpa_auth_callbacks for mesh was missing a for_each_sta
implementation. This is an issue with pmksa cache, as when a cache entry
expires the for_each_sta callback is called in order to clear the pmksa
reference for all sta that was using this entry. Not having a
for_each_sta callback will prevent this cleanup to happen then a sta
could still use this pmksa entry even after it has been freed.
