reiserfs: Clean up xattrs when REISERFS_FS_XATTR is unset
The current reiserfs xattr implementation will not clean up old xattr files if files are deleted when REISERFS_FS_XATTR is unset. This results in inaccessible lost files, wasting space. This patch compiles in basic xattr knowledge, such as how to delete them and change ownership for quota tracking. If the file system has never used xattrs, then the operation is quite fast: it returns immediately when it sees there is no .reiserfs_priv directory.
