contrib/elf2dmp: add kernel start address checking
Before this patch, if elf2dmp failed to find NT kernel PE magic in allowed virtual address range, then it assumes NULL as NT kernel address and cause segfault. This patch fix the problem described above by checking NT kernel address before futher processing.
