hfsplus: fix rename over directories
When renaming over a directory we need to use hfsplus_rmdir instead of hfsplus_unlink to evict the victim. This makes sure we properly error out on non-empty directory as required by Posix (BZ #16571), and it also makes sure we do the right thing in case i_nlink will every be set correctly for directories on hfsplus.
