[Qemu-block] [PULL 29/29] blkdebug: Don't confuse image as backing file

[Kevin Wolf]

From: Fam Zheng <address@hidden>

The word "backing file" nowadays refers to the backing_hd in the
external snapshot sense (i.e. bs->backing_hd), instead of the file sense
(bs->file). Correct the comment to use the right term.
