libdiskfs: Don't warn if requesting shutdown notification fails with EPERM
The code already ignores proc_mark_important failing with EPERM; do the
same for opening /servers/startup and startup_request_notification. All
of these calls will fail for unprivileged mounts.
Also plug a port leak: we want to deallocate the "init" port whether the
RPC succeeds or not.
