ksmbd: contain default data stream even if xattr is empty

ksmbd: contain default data stream even if xattr is empty

commit 1ec72153ff434ce75bace3044dc89a23a05d7064 upstream.

If xattr is not supported like exfat or fat, ksmbd server doesn't
contain default data stream in FILE_STREAM_INFORMATION response. It will
cause ppt or doc file update issue if local filesystem is such as ones.
This patch move goto statement to contain it.
