wifi: iwlwifi: mvm: update station's MFP flag after association

[ Upstream commit 5a86dcb4a908845e6b7ff39b78fb1141b895408f ]

The management frames protection flag is always set when the station
is not yet authorized. However, it was not cleared after association
even if the association did not use MFP. As a result, all public
action frames are not parsed by fw (which will cause FTM to fail,
for example). Update the station MFP flag after the station is
authorized.
