drm/xe/guc: Fail immediately on GuC load error

By using the same variable for both the return of poll_timeout_us and
the return of the polled function guc_wait_ucode, the return value of
the latter is overwritten and lost after exiting the polling loop. Since
guc_wait_ucode returns -1 on GuC load failure, we lose that information
and always continue as if the GuC had been loaded correctly.

This is fixed by simply using 2 separate variables.
