[PATCH 3/3] btrfs-progs: mfks-tests: make sure mkfs.btrfs cleans up temporary chunks

[Qu Wenruo <wqu@suse.com>]

Since current "btrfs filesystem df" command will warn if there are
multiple profiles of the same type, it's a good way to detect left-over
temporary chunks.

This patch will enhance the existing mkfs-tests/001-basic-profiles test
case to also check for the warning messages, to make sure mkfs.btrfs has
properly cleaned up all temporary chunks.
