kernfs: make kernfs_walk_ns() use kernfs_pr_cont_buf[]
kernfs_walk_ns() uses a static path_buf[PATH_MAX] to separate out path
components. Keeping around the 4k buffer just for kernfs_walk_ns() is
wasteful. This patch makes it piggyback on kernfs_pr_cont_buf[]
instead. This requires kernfs_walk_ns() to hold kernfs_rename_lock.
