drm/xe/guc: Fail immediately on GuC load error
[ Upstream commit 9b72283ec9b8685acdb3467de8fbc3352fdb70bb ]
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.
Fixes: a4916b4da448 ("drm/xe/guc: Refactor GuC load to use poll_timeout_us()")
