Commit Message

Currently we only retry to load GuC firmware if the load fails due to
timeout. On Gen9 GuC loading may fail for different reasons, not just
hang/timeout. Direction from the GuC team is to retry for all cases of
GuC load failure on Gen9, not just for timeout.

Worst case is we get the same error 3 times before giving up.
