m68k: rename global variable vmalloc_end to m68k_vmalloc_end
On SUN3, m68k defines macro VMALLOC_END as unsigned long variable
vmalloc_end which is adjusted from mmu_emu_init(). This becomes
problematic if a local variables vmalloc_end is defined in some
function (not very unlikely) and VMALLOC_END is used in the function -
the function thinks its referencing the global VMALLOC_END value but
would be referencing its own local vmalloc_end variable.
Rename the global variable to m68k_vmlloc_end which is much less
likely to be used as local variable name.
