s390/vmalloc: fix VMALLOC_START calculation

Browse source

With the introduction of the module area on top of the vmalloc area, the
calculation of VMALLOC_START in setup_memory_end() function hasn't been
adjusted. As a result we got vmalloc area 2 Gb (MODULES_LEN) smaller than
it should be and the preceding vmemmap area got extra memory instead.
The patch fixes this calculation error although there were no visible
negative effects.
Apart from that, change 'tmp' variable to 'vmemmap' in memory_end
calculation for better readability.
