Convert IrqVectorRegistration from a devres-managed internal type to a lifetime-annotated type that owns the PCI interrupt vector allocation. Dropping it frees the vectors. IrqVector gains a reference to the IrqVectorRegistration it was derived from. Since index() borrows the registration, the compiler prevents the allocation from being dropped while any IrqVector (and hence any irq::Registration built from it) is still live. alloc_irq_vectors() returns IrqVectorRegistration<'_> directly, giving drivers explicit control over the allocation lifetime, which is needed by net and block drivers that re-allocate vectors at runtime, e.g. during queue reconfiguration or device recovery.
