Preparations to caching root in path_walk()

Split do_path_lookup(), opencode the call from do_filp_open()
do_filp_open() is the only caller of do_path_lookup() that
cares about root afterwards (it keeps resolving symlinks on
O_CREAT path after it'd done LOOKUP_PARENT walk).  So when
we start caching fs->root in path_walk(), it'll need a different
treatment.
