leds: uleds: Return -EFAULT on copy_to_user() failure
uleds_read() copies the current brightness value to userspace but
ignores copy_to_user() failures. It then clears the pending update and
reports a successful full read even when no data was copied.
Return -EFAULT when the copy fails and leave the update pending so a
later read can retry.
