wifi: iwlwifi: mvm: send TX path flush in rfkill

[ Upstream commit 2afc3dad39ea84a072d04ff40a417234326adc47 ]

If we want to drop packets, that's surely a good thing to
do when we want to enter rfkill. Send this command despite
rfkill so we can successfully clean up everything, we need
to handle it separately since it has CMD_WANT_SKB, so it's
not going to automatically return success when in rfkill.
