Move wpa_sm_remove_pmkid() call to PMKSA cache entry freeing

Browse source 
This makes it clearer that the PMKSA caching entry gets removed from
the driver regardless of how the internal entry from wpa_supplicant
gets cleared. In practice, this call was skipped only for the case
when the entry for the current AP was being updated, so the previous
version was likely to work with all drivers. Anyway, it is cleaner
to explicitly remove the old entry even in that case before the new
entry gets added.
