s390/checksum: support GENERIC_CSUM, enable it for KASAN
This is the s390 variant of commit d911c67e10b4 ("x86: kasan: kmsan:
support CONFIG_GENERIC_CSUM on x86, enable it for KASAN/KMSAN"). Even
though most of the s390 specific checksum code is written in C there is
still the csum_partial() inline assembly which could prevent KASAN and
KMSAN from seeing all memory accesses.
Therefore switch to GENERIC_CSUM if KASAN is enabled just like x86.
