USB: xhci: Remove unnecessary reads of IRQ_PENDING register.
Remove a duplicate register read of the interrupt pending register from
xhci_irq(). Also, remove waiting on the posted write of that register.
The host will see it eventually. It will probably read the register
itself before deciding whether to interrupt the system again, forcing the
posted write to complete.
