You could switch back to synchronous firmware loading soon, as it's not

But until then, the proper fix for this is going to be to cancel the
waiter earlier in teardown.

I don't think we found a way when we looked at this, and instead made
the module unload wait for the request_firmware callback to come back
(see all users of the request_firmware_complete struct member in
iwlwifi/iwl-drv.c)
