[BUG]
misc-test/021 will fail with the following error message:
====== RUN CHECK root_helper btrfs-progs/btrfs-image -r btrfs-progs/tests//test.img /dev/loop2
ERROR: failed to enlarge result image: Invalid argument
ERROR: failed to fix chunks and devices mapping, the fs may not be mountable: Invalid argument
extent buffer leak: start 30638080 len 16384

WARNING: dirty eb leak (aborted trans): start 30408704 len 16384
ERROR: restore failed: Invalid argument
failed: root_helper btrfs-progs/btrfs-image -r btrfs-progs/tests//test.img /dev/loop2
test failed for case 021-image-multi-devices
[CAUSE]
For misc-test/021, we're using loopback device, which doesn't support
ftruncate. That's why it returns EINVAL.
[FIX]
Only call ftruncate64() if we're operating on a regluar file.
Fixes: a7a44164c84e ("btrfs-progs: image: Use correct device size when restoring")
