selftests/mm/vm_util.c: correct __pagemap_scan_get_categories return value

Browse Source 
Currently __pagemap_scan_get_categories returns the result from the ioctl
call which should be an int, not uint64_t.  The ioctl may return -1 on
error, which will be interpreted as UINT64_MAX.  Adjust the return type to
use the correct value.
