iothread: Make iothread_stop() idempotent
Currently, iothread_stop_all() makes all iothread objects unsafe
to be destroyed, because qemu_thread_join() ends up being called
twice.
To fix this, make iothread_stop() idempotent by checking
thread->stopped.
Fixes the following crash:
qemu-system-x86_64 -object iothread,id=iothread0 -monitor stdio -display none
QEMU 2.10.50 monitor - type 'help' for more information
(qemu) quit
qemu: qemu_thread_join: No such process
Aborted (core dumped)
