qcacld-3.0: Fix WME ParamSetCount error

qcacld-2.0 to qcacld-3.0 propagation

During the WFA WME test, the ParamSetCount in beacon
IE is mismatch with the value in ASSOC response.
The root cause is the value will be updated when
station gets connected no matter the WME parameter
changing or not.
The fix is to avoid updating the ParamSetCount count
when there is no change in the WME parameters.
