> The current logic for handling resets is more complicated than it needs
> to be. The deferred_reset flag is used to indicate a reset is needed
> and the deferred_reset_state is the requested, post-reset, state. The
> source of the requested reset isn't immediately obvious. Improve
> readability by replacing deferred_reset_state with deferred_reset_type,
> which can be either PDS_VFIO_DEVICE_RESET (initiated/requested by the
> DSC) or PDS_VFIO_HOST_RESET (initiated/requested by the VMM).
