Subject: [PATCH] wl12xx: schedule recovery on command timeout
We use a long timeout (2 seconds) when sending commands to the FW.
When a command times out, it means the FW is stuck, and we should
commence recovery.
This should make recovery times shorter as we'll recover on the first
timeout indication.
