[PATCH] c-user: Add & update ratemon get return values

[Martin Erik Werner]

Add a description of the previously missing RTEMS_NOT_DEFINED return
value for rtems_rate_monotonic_get_status().

Update the RTEMS_SUCCESSFUL return value descriptions for
rtems_rate_monotonic_get_status() and
rtems_rate_monotonic_get_statistics() which incorrectly used the same
description as rtems_rate_monotonic_period().
