vppinfra: fix page boundary crossing bug in hash_memory64

Fix a day-1 bug, possibly dating back as far as 2002. The zap64() game
involves fetching 8 byte chunks, and clearing octets not to be
included in the key.

That's fine *unless* the 8-byte fetch happens to cross a page boundary
into unmapped or no-access space.

Type: fix
