Subject: [PATCH] Improve logging to debug invalid "extra_specs" entries
When volume creation fails due to invalid extra_specs entry,
it's hard to find a mismatch between extra_specs and capabilities
exposed by multiple hosts. This additional log printing will
help to detect a root cause of the failure.
