s390/vmem: do not silently ignore mapping limit
The only interface that allows drivers establishing
liner mappings is vmem_add_mapping(). It does check
a requested range against allowed limits and a call
to modify_pagetable() with an invalid mapping range
is impossible.
Hence, an attempt to map an address range outside of
the identity mapping or vmemmap array could only be
kernel bug.
