USB: EHCI: Cleanup and rewrite ehci_vdgb().
The vdbg macro is not used anywhere so it can be removed. With pre-release GCC-4.6, there are several complaints of variables that are 'set but not used' caused by the ehci_vdbg() macro expanding to something that does not contain any of its arguments. We can quiet this warning by rewriting ehci_vdbg() as a variadic static inline that does nothing.
