nsfs: clean-up ns_get_path() signature to return int
ns_get_path() and ns_get_path_cb() only ever return either NULL or an
ERR_PTR. It is far more idiomatic to simply return an integer, and it
makes all of the callers of ns_get_path() more straightforward to read.
Fixes: e149ed2b805f ("take the targets of /proc/*/ns/* symlinks to separate fs")
