I think for many wireless devices the workqueue, like for iwldvm that
was just changed, isn't in the packet path and thus less relevant.

For some, like SDIO based chips, it's more likely to be in the packet
path, so it would make sense to keep it.

Of course there's always a possibility of getting disconnected and then
not being able to re-establish the connection in memory pressure, but
that's not something we can control/predict (the disconnection). Can of
course also happen with wired if somebody pulls out the cable, but it's
less reliant on memory allocations to get back to working there, I
guess :)
