usb: chipidea: Prevent unbalanced IRQ disable

[ Upstream commit 8b97d73c4d72a2abf58f8e49062a7ee1e5f1334e ]

The ChipIdea IRQ is disabled before scheduling the otg work and
re-enabled on otg work completion. However if the job is already
scheduled we have to undo the effect of disable_irq int order to
balance the IRQ disable-depth value.
