USB: EHCI: fix handling of dead controllers

This patch (as1165) makes a few small changes in the logic used by
ehci-hcd when it encounters a controller error:

	Instead of printing out the masked status, it prints the
	original status as read directly from the hardware.

	It doesn't check for the STS_HALT status bit before taking
	action.  The mere fact that the STS_FATAL bit is set means
	that something bad has happened and the controller needs to
	be reset.  With the old code this test could never succeed
	because the STS_HALT bit was masked out from the status.

I anticipate that this will prevent the occasional "irq X: nobody cared"
problem people encounter when their EHCI controllers die.
