ALSA: hda - Add enable_msi=0 workaround for four HP machines
commit 693e0cb052c607e2d41edf9e9f1fa99ff8c266c1 upstream. While enabling these machines, we found we would sometimes lose an interrupt if we change hardware volume during playback, and that disabling msi fixed this issue. (Losing the interrupt caused underruns and crackling audio, as the one second timeout is usually bigger than the period size.) The machines were all machines from HP, running AMD Hudson controller, and Realtek ALC282 codec.
