Since we do not immediately update uc_fw->load_status after full GPU
reset we have a small window of time during re-initialization where this
function would falsely return true. We don't hit the issue in this
patch, but I'd personally prefer not to add this function until
uc_fw->load_status is correctly updated as we might inadvertently start
to use it at the wrong time. Alternatively, if you want to merge this
soon we could read the status from the HW as an initial version and then
switch to uc_fw->load_status after we've fixed it.
