Create volume from snapshot : Get mismatched form after a invalid submission

[lijunli]

Version: Mitaka

Steps to reproduce:

1. Go to Project -> Volumes Snapshots
2. Pick an existing snapshot, click "Create Volume" and get a modal form
3. Enter an invalid value(for example, a value which is smaller than the original size) for "Size(Gib)" field and click "Create Volume"
4. Get another modal form with a warning message "The volume size cannot be less than the
snapshot size(2GiB)."

Expected:
4. You should get the same modal form with step 2 except the warning message.

Actually:
The forms in step 2 and 4 are different.

Hi Lijun,

Can you verify this behavior in Newton? I tried it out, and it seemed to work normally.

Hi Cindy,

I have verified this bug in Newton just now. It does exist！

This is still occurring on the current master. The form that is shown after the error is also titled 'Create Volume', but it has different fields, and does not retain the volume source of the original form, i.e. it has forgotten that the volume source is the snapshot.
