Resending patch with decreasing coroutine pool size on device remove
We encountered random disk IO performance drop since qemu-5.0.0, and this patch
fixes it.
Commit message in 4d68e86b implied to adjust coroutine pool size adaptively, so
I tried to implement this.
Changes from v3:
No code changed. Changed commit message so that first line indicates to
correct commit ID.
Changes from v2:
Decrease coroutine pool size on device remove
Changes from v1:
Use qatomic_read properly
