nilfs2: return EBUSY against delete request on snapshot
This helps userland programs like the rmcp command to distinguish
error codes returned against a checkpoint removal request.
Previously -EPERM was returned, and not discriminable from real
permission errors. This also allows removal of the latest checkpoint
because the deletion leads to create a new checkpoint, and thus it's
harmless for the filesystem.
