Do not allow to modify access for public share type

Now public share type can be removed project access, but when
listing access, manila returns 'Access list not available for public
share types'. It's weird for users experience.

We should check if a type is public and do not allow public share type
to modify project access.

When modifying access for public share type, API will return 409 and message:
"Invalid share type: Type access modification is not applicable to public
share type."
