drm/xe/gsc: Fix FW status if the firmware is already loaded

drm/xe/gsc: Fix FW status if the firmware is already loaded

We set the FW status to "TRANSFERRED" after the load completes and to
"RUNNING"once we're done with proxy init, so do the same if we're trying
to re-load the FW and it is already loaded.

Note that there is no difference in driver behavior between the 2
states, but it's useful to be accurate when we dump the status for
debug.
