numa01.sh: numademo fixes

1) numademo does not accept a 'msize' argument. I think it was an initial
typo mistake that numanode was invoked as
  numanode -c msize
instead of
  numanode -c ${msize}k

2) I think test07 should return TPASS if $x is 0 (not 1), because this test
verifies that after execution of `numanode` the OS updates interleave_hit
values of each of the nodes. And if a node doesn't get a minimum increase,
then it's a failure.
