[PATCH] Prevent trident driver from grabbing pcnet32 hardware

[Jon Mason]

Some pcnet32 hardware erroneously has the Vendor ID for Trident.  The
pcnet32 driver looks for the PCI ethernet class before grabbing the
hardware, but the current trident driver does not check against the
PCI audio class.  This allows the trident driver to claim the pcnet32 
hardware.  This patch prevents that.

This patch is untested on Trident 4DWAVE_DX hardware, but has been
tested on pcnet32 hardware.

Thanks,
Jon
