iavf: Refactor iavf state machine tracking
[ Upstream commit 45eebd62999d37d13568723524b99d828e0ce22c ]
Replace state changes of iavf state machine
with a method that also tracks the previous
state the machine was on.
This change is required for further work with
refactoring init and watchdog state machines.
Tracking of previous state would help us
recover iavf after failure has occurred.
