drm/xe: Increase log level for unhandled page faults

Set the kernel log level for unhandled page faults to match the log
level (info) for engine resets. Currently, dmesg output can be confusing
because it shows an engine reset without indicating the page fault that
caused it. Without this change, the GuC log must be examined to
determine the source of the engine reset.
