[JFFS2][XATTR] Fix memory leak with jffs2_xattr_ref
If xattr_ref is associated with an orphan inode_cache on filesystem mounting, those xattr_refs are not released even if this inode_cache is released. This patch enables to call jffs2_xattr_delete_inode() for such a irregular inode_cachde too. Signed-off-by: KaiGai Kohei <kaigai@ak.jp.nec.com> Signed-off-by: David Woodhouse <dwmw2@infradead.org>
