btrfs-progs: mkfs: do not truncate the image when --rootdir is set
With the rootdir option we try to guess the final size of the image and
fill it with zeros, preceded by truncation. After patch
"Btrfs-progs: Do not force mixed block group creation unless '-M' option
is specified"
the misc test 002 will fail, because of the non-mixed mode. I think we
should not touch the image size (no change for block devices) and try to
fit into whatever is provided by user.
