[PATCH] USB: UHCI: Remove unused fields and unneeded tests for NULL

This patch (as562) removes from the uhci-hcd driver a few unused fields
and some unnecessary tests against NULL and assignments to NULL.  In fact
it wasn't until fairly recently that the tests became unnecessary.
Before last winter it was possible that the driver's stop() routine would
get called even if the start() routine returned an error, but now that
can't happen.  Hence there's no longer any need to check for partial
initialization.
