I tried reproducing this
Here are my observations
[stack@controller devstack]$ nova suspend test
[stack@controller devstack]$ nova list

[stack@controller devstack]$ nova resume test && nova volume-detach

ERROR (Conflict): Cannot 'detach_volume' instance
a3e5e950-a51f-483a-ac48-85203bdb0bc9 while it is in vm_state suspended (HTTP
409) (Request-ID: req-8049116f-3e4c-476e-a475-9e67c874e65f)
As you can see that in this case the detach_volume did not go through because
of the state suspended.

2、Reproduce steps:
a) Boot an instance
b) attach an volume to the instance
c) shut off the instance
d) start the instance and detach the volume quickly until return success
e) login the instance find the volume of vdb is still exsit and can be used.
f) show the volume status have been from in-used to avaiable
