wifi: iwlwifi: mvm: fix the FCS truncation logic in d3

Browse Source 
Fix a harmless mistake in the wake packet management code in the d3
wakeup flow. If the FCS is truncated, we want to detect it, but we
cleared the icvlen before updating the truncated variable that holds the
number of bytes having been truncated.
Fix that.
