Oh, this is one of the series locks for the removal of big qemu lock.
The degradation of big lock will take several steps, including to
introduce device's private lock. Till then, when the device add path
from iothread and the remove path in io-dispatch is out of the big
qemu lock. We need this extra lock.
These series is too big, so I send out the 1st phase for review.
