[PATCH] msacm32: Reduce block align condition scope to test covered drivers

[Bruno Jesus]

MP3 files have different block sizes due to padding, this causes problems for apps that play mp3 audio (eg Morrowind / Oblivion). Instead of reversing the patch reduce the test scope to what we currently have tests for. After 2.0 I'll resume my work on finding wheather the test is correct there or should happen inside the driver.

Fixes a regression introduced by
