UBUNTU SAUCE: (no-up) linux/ena: Add NUMA aware interrupt allocation

BugLink: https://bugs.launchpad.net/bugs/2085159

This patch implements an improved allocation strategy for IO interrupts,
taking into account the physical device NUMA node.
Also, it replaces the use of a deprecated API (irq_set_affinity_hint)
which enforces affinity with a newer API (irq_update_affinity_hint)
which only hints at the preferred CPU mask.
