Tai-hwa Liang 2acbe67787 sound(4): fixing panic for INVARIANTS kernel 
3e7bae0821 turns the BUS_READ_IVAR() failure from a warning into a
KASSERT.  For certain PCI audio devices such like snd_csa(4) and
snd_emu10kx(4), the ac97_create() keeps the device handler generated
by device_add_child(pci_dev, "pcm"), which is not really a PCI device
handler.  This in turn causes the subsequent pci_get_subdevice()
inside ac97_initmixer() triggering a panic.

This patch tries to put a bandaid for the aforementioned pcm device
children such that they can use the correct PCI handler(from parent)
to avoid a KASSERT panic in the INVARIANTS kernel.

Tested with:	snd_csa(4), snd_ich(4), snd_emu10kx(4)
