Treat copy_file_range() return value of zero as an error: it indicates that no bytes could be copied (perhaps the source file is shorter than expected), and the existing retry loop would otherwise spin forever since nwritten would never reach BLCKSZ. The other uses of copy_file_range() in the tree don't have this problem.
