[PATCH 2/2] tools/x86: Fix some potential undefined behavior

From: Numfor Mbiziwo-Tiapo If insn_init is given a NULL kaddr and 0 buflen then validate_next will perform arithmetic on NULL, add a guard to avoid this. Don't perform unaligned loads in __get_next and __peek_nbyte_next as these are forms of undefined behavior. These problems were identified
