Public bug reported:

When there is a race for a volume between 2 or more instances, it is
possible for more than one to pass the API check. All of them will get
scheduled as a result, and only one will actually successfully attach
the volume, while others will go to ERROR.

This is not ideal since we can reserve the volume in the API, thus
making it a bit more user friendly when there is a race (the user will
be informed immediately instead of seeing an errored instance).
