Rename the function so its name falls in line with the rest of btrfs
nomenclature. So when we change the uuid of the header it's in fact
of the buffer header. Also remove the root argument since it's used
solely to take a reference to fs_info which can be done via the
mandatory eb argument. No functional changes.
