ovl: lookup whiteouts outside iterate_dir()
If jffs2 can deadlock on overlayfs readdir because it takes the same lock
on ->iterate() as in ->lookup().
Fix by moving whiteout checking outside iterate_dir(). Optimized by
collecting potential whiteouts (DT_CHR) in a temporary list and if
non-empty iterating throug these and checking for a 0/0 chardev.
