ioctl: add note regarding CLONE_RANGE(len=0) behaviour
A BTRFS_IOC_CLONE_RANGE request with a src_length value of zero has the
effect of cloning all data from src_offset through to end-of-file.
Document this behaviour in the header file for those who (like me)
incorrectly assume that no data is cloned in such a case.
