thread-pool: use ThreadPool from the running thread

Use qemu_get_current_aio_context() where possible, since we always
submit work to the current thread anyways.

We want to also be sure that the thread submitting the work is
the same as the one processing the pool, to avoid adding
synchronization to the pool list.
