Aun-Ali Zaidi 2fe8a0c519 ANDROID: ASoC: msm: qdsp6v2: Fix memset argument order.
With commit f6896ad1b5966405e87ef668922cadddad52f2eb, an incorrectly ordered
memset() command was present. This causes compilation to fail on GCC 5+.

Fix the order of the passed parameters to properly set requested memory.

BUG=38500815
TEST= Kernel compiles and boots bullhead.
