xhci: unify cycle state toggling operation with 'XOR'

Browse source

Some toggling operation in xHCI driver still use conditional toggling:
ring->cycle_state = (ring->cycle_state ? 0 : 1);

Use XOR to invert the cycle state instead of a conditional toggle to unify
cycle state toggling operation in xHCI driver.
