dsc-drivers: update ionic drivers to 24.03.4-003#45

Conversation
Under a large scale use we found that the check for a missed doorbell
was taking too much CPU, so we reworked the check to use a per-device
timer rather than a per-queue timer.
Internal patches:
ionic: remove missed doorbell per-queue timer
ionic: add per-device doorbell timer
ionic: tighter test for active napi
ionic: platform doorbell timer setup

A little bit of code cleanup, plus a fix to move the missed
doorbell handling to the cpu last used by the AdminQ napi.
Internal patches:
ionic: fix up a few bits left from doorbell fix fix
ionic: push work items to adminq CPU
ionic: back off doorbell check timer

This is a combination of the earlier 24.03.4-002 patch and a refinement that makes sure the doorbell checking workqueue activity happens on the same cpu as the last AdminQ napi for a particular device. This makes sure that the activity is following any related irqbalance movements of the device's cpu assignments.
