rust: pci: resolve IRQ in index() and embed IrqRequest in IrqVector

Browse source

Move the pci_irq_vector() call from the TryInto<IrqRequest> impl into
IrqVectorRegistration::index(), so the IRQ number is resolved eagerly.

IrqVector now embeds the resolved IrqRequest and a reference to the
IrqVectorRegistration. The conversion to IrqRequest is infallible, which
removes the need for pin_init_scope() in request_irq() /
request_threaded_irq().
