Alexander Egorenkov 64539853ca zdump/dfi: Fix potential illegal memory access in kdump_init() ...

Before reading data at addresses 0x10418 and 0x10420 in kdump_init(),
validate the validity of the memory range. Otherwise this can result in
a segmentation fault when zgetdump is given a very small dump, e.g.
S390 DASD single-volume dump of size 0x1000 bytes.
