haven: rm: Add calls to relase/reclaim IRQs

A VM may release a lent IRQ back to its lender. The lendee VM notifies
the resource manager that it may give the interrupt back to the lender
via its interrupt handle. The lender then must notify the lender VM that
it has released the interrupt. The lender VM must then reclaim the
interrupt via the handle.
