[PATCH] USB: ehci: fix bogus alteration of a local variable

In a rare and all-but-unused path, the EHCI driver could reuse a variable
in a way that'd make trouble.  Specifically, if the first root hub port
gets an overcurrent event (rare) during a remote wakeup scenario (all but
unused in today's Linux, except for folk working with suspend-to-RAM and
similar sleep states), that would look like a fatal error which would shut
down the controller.  Fix by not reusing that variable.
