s390: avoid undefined behaviour
At a couple of places smatch emits warnings like this:
arch/s390/mm/vmem.c:409 vmem_map_init() warn:
right shifting more than type allows
In fact shifting a signed type right is undefined. Avoid this and add
an unsigned long cast. The shifted values are always positive.
