[PATCH 0/1] MR8110: amstream: Fix allocator pitch tests.

[PATCH 1/1] amstream: Fix allocator pitch tests.

[Elizabeth Figura]

From: Elizabeth Figura

For some reason ddraw alignment, at least for RGB555 surfaces, varies between
32-bit and 64-bit (and, bizarrely, 64-bit has *less* alignment).

Fix the tests here to compare against the ddraw pitch rather than hardcoding
the expected pitch.
