coroutine: let CoQueue wake up outside a coroutine 

The assert() was added in commit b681a1c73e ("block: Repair the
throttling code."), when the qemu_co_queue_do_restart() function
required to be running in a coroutine. It was later made unnecessary in
commit a9d9235567 ("coroutine-lock: reschedule coroutine on the
AioContext it was running on").
