[PATCH 4/4] btrfs-progs: clean the unnecessary error msg of btrfs-file-show

[Gui Hecheng <guihc.fnst@cn.fujitsu.com>]

If the new version of btrfs-file-show fails, it will try to use the
old version. But before that, an error msg of the failed ioctl
shows up which causes xfstests case btrfs/006 to get a mismatch output.
I think we can just remove the error msg since the btrfs-file-show
still works with right outputs. Showing an error msg together with
the right result is really awkward.
