Currently, we xe_ras_process_errors() inside xe_ras_init() to handle boot
time errors. But this can potentially result in declaring the device as
wedged quite early in the driver load sequence, which is problematic due to
the lack of registered drm device or required wedged cleanup hooks at this
point.

Call xe_ras_process_errors() only after the prerequisites are available.
