ALSA: hdsp: don't disable if not enabled

Browse Source 
[ Upstream commit 507cdb9adba006a7798c358456426e1aea3d9c4f ]

hdsp wants to disable a not enabled pci device, which makes kernel
throw a warning. Make sure the device is enabled before calling disable.

[    1.758292] snd_hdsp 0000:00:03.0: disabling already-disabled device
