ionic: Keep interrupt affinity up to date

Currently the driver either sets the initial interrupt affinity for its
adminq and tx/rx queues on probe or resets it on various
down/up/reconfigure flows. If any user and/or user process
(i.e. irqbalance) changes IRQ affinity for any of the driver's interrupts
that will be reset to driver defaults whenever any down/up/reconfigure
operation happens. This is incorrect and is fixed by making 2 changes:

1. Allocate an array of cpumasks that's only allocated on probe and
   destroyed on remove.
2. Update the cpumask(s) for interrupts that are in use by registering
   for affinity notifiers.
