iwlwifi: mvm: write queue_sync_state only for sync
[ Upstream commit 97cc169 ] We use mvm->queue_sync_state to wait for synchronous queue sync messages, but if an async one happens inbetween we shouldn't clear mvm->queue_sync_state after sending the async one, that can run concurrently (at least from the CPU POV) with another synchronous queue sync.
