[PATCH] USB: dummy_hcd: rename variables

The recent platform_device update has reintroduced into dummy_hcd.c the
dreaded dev->dev syndrome.  This harkens back to when an earlier version
of that driver included the unforgettable line:

	dev->dev.dev.driver_data = dev;

This patch (as602) renames the platform_device variables to "pdev", in
the hope of reducing confusion.
