wifi: cfg80211: set correct param change count in ML element

The ML element generation code to create a BSS entry from a per-STA
profile was not overwriting the BSS parameter change count. This meant
that the incorrect parameter change count would be reported within the
multi-link element.

Fix this by returning the BSS parameter change count from the function
and placing it into the ML element. The returned tbtt info was never
used, so just drop that to simplify the code.
