Do not flush PMKSA cache on restoring dedicated per-ESS MAC address

Browse source 
Now that we check in PMKSA cache code whether the entry was created for
the same local address, it is fine to leave the old entries in the cache
even if we have changed addresses. This allows a valid PMKSA cache entry
to be used when restoring the same MAC address for the same ESS.
