audio: Fix crash due to invalid Splitter size

Fix crash caused by reading incorrect size of Splitter data.

In most games the crash doesnt happen if you have nn::audio::AudioRendererParameter VoiceCount aligned to 2, as that causes splitter data to be aligned by 0x10, but otherwise, the alignment by 0x10 done in SplitterContext->Update may exceed SplitterSize (which was previously labeled as Unknown24), causing a crash.

(Crash can be replicated by doing AudioRendererParameter.voiceCount++; in any SDK 20.X game that works, which doesn't cause crash on actual hardware)

(This patch is from a friend who makes mods.)
