vm_page: Fix loading bad memory addresses from file
When loading bad memory addresses from a file, we are passed an end
pointer that points on the first byte after the buffer. We want the
buffer to be null-terminated (by changing the last byte to \0 if it is
reasonable to do so), so adjust the end pointer to be on that byte.
