4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Richard Weinberger <richard@nod.at>
commit 29b7a6fa1ec07e8480b0d9caf635a4498a438bf4 upstream.
At this point UBI volumes have already been free()'ed and fastmap can no longer access these data structures.
