s390/mem_detect: rely on diag260() if sclp_early_get_memsize() fails
[ Upstream commit eb33f9eb304a4c18beb5ba6362eaa5c4beaf40d8 ]
In case sclp_early_get_memsize() fails but diag260() succeeds make sure
some sane value is returned. This error scenario is highly unlikely,
but this change makes system able to boot in such case.
