[PATCH] kselftests: dmabuf-heaps: Fix confused return value on expected error testing

[John Stultz]

When I added the expected error testing, I forgot I need to set
the return to zero when we successfully see an error.

Without this change we only end up testing a single heap
before the test quits.
