wifi: iwlwifi: mvm: copy the correct TK length for ranging

When setting the TK for ranging with an associated peer, 32 bytes of
TK are copied from the vif key without verifying the actual key length
which may be only 16 bytes if CCMP-128 is used. Fix it by setting the
copy length according to the key cipher.
