sound fixes for 5.0-rc5

Browse Source 
Only three fixes: a fix for Realtek HD-audio looks lengthy, but it's
 just a code shuffling, and the actual changes are fairly small.  The
 rest are a PCM core fix for a long-standing bug that was recently
 scratched by syzkaller, and a trivial USB-audio quirk for DSD
 support.
