There are also cases, e.g. when loading with disable_11ax=1, where the pointer might be NULL but we still attempt to use it, causing a crash.

However, in iwl_mvm_queue_state_change() we're often called with them enabled, e.g. from flush if anything was flushed, triggering a mac80211 warning. Fix that by disabling the softirqs across the TX call.
