tests: Fix sample mismatch test to fail again
tests: Fix sample mismatch test to fail again

The change to the render framework that fixed the number
of samples in the renderpass caused the sample mismatch
test to start "failing" by not seeing the expected error.
Changing num samples in the pipeline ms state in the test
is the easiest fix.
