io_uring: remove IO_WQ_WORK_CB
IO_WQ_WORK_CB is used only for linked timeouts, which will be armed before the work setup (i.e. mm, override creds, etc). The setup shouldn't take long, so it's ok to arm it a bit later and get rid of IO_WQ_WORK_CB. Make io-wq call work->func() only once, callbacks will handle the rest. i.e. the linked timeout handler will do the actual issue. And as a bonus, it removes an extra indirect call.
