tests: only update last_byte when at the edge
The only possible change of last_byte is when it reaches the edge.
Setting it every time might let last_byte contain an invalid data when
memory corruption is detected, then the check of the next byte will be
incorrect. For example, a single page corruption at address 0x14ad000
will also lead to a "fake" corruption at 0x14ae000:
Memory content inconsistency at 14ad000 first_byte = 44 last_byte = 44 current = ef hit_edge = 0
Memory content inconsistency at 14ae000 first_byte = 44 last_byte = ef current = 44 hit_edge = 0
After the patch, it'll only report the corrputed page:
Memory content inconsistency at 14ad000 first_byte = 44 last_byte = 44 current = ef hit_edge = 0
