drm/panthor: return error on truncated firmware

Browse source

panthor_fw_load() detects truncated firmware images, but jumps to the
common cleanup path without setting ret. If no previous error was recorded,
the function can return 0 and treat the invalid firmware as successfully
loaded.

Set ret to -EINVAL before leaving the truncated-image path.
