Vasily Gorbik 6ce9a22fc0 s390/mem_detect: fix detect_memory() error handling ...

[ Upstream commit 3400c35a40 ]

Currently if for some reason sclp_early_read_info() fails,
sclp_early_get_memsize() will not set max_physmem_end and it
will stay uninitialized. Any garbage value other than 0 will lead
to detect_memory() taking wrong path or returning a garbage value
as max_physmem_end. To avoid that simply initialize max_physmem_end.
