nl80211: Do not add WMM parameters when updating an existing STA entry

Browse source 
In the case of the driver not supporting full AP mode STA state (i.e.,
not adding a STA entry before association), the QoS parameters are not
allowed to be modified when going through (re)association exchange for a
STA entry that has not been removed from the kernel. cfg80211 would
reject such command to update STA flags, so do not add the WMM parameter
in this case.
