btrfs-progs: corrupt-block: Add support for handling specific root when using -K option
Currently the -K option supports corrupting items only in the default
root (which is the root tree). This makes it impossible to test the
free-space recovery (or any other) code for that matter. Fix it by
using the root corresponding to the one passed in -r (if any).
