[PATCH 2/4] btrfs-progs: btrfsck: Print which filesystem to be checked to stdout

[Dieter Ries <mail@dieterries.net>]

This patch makes btrfsck print the filesystem, which is to be checked,
to stdout, as well as the UUID of the corresponding partition.
This should be helpful when analyzing (copied and pasted) output of
btrfsck.
