[S390] qdio: remove superfluous log entries and WARN_ONs.
* Don't write debug feature log entries for sl, slsb and sbal since these elements can be located from the qdio_q pointer which is also logged. * Convert WARN_ON for wrong alignment of sbal to BUG_ON. * Remove WARN_ON's for wrong alignment of q / qib / slib since these alignments should be guaranteed by kmem_cache_alloc alignment / struct aligned attribute / __get_free_page.
