[PATCH] drm/xe/guc: Demote uncorrectable local error log to info

[Varun Gupta]

The UNCORRECTABLE_LOCAL_ERROR notification sent by the GuC indicates a
local, queue-level context termination rather than a global device or
driver failure. This can be triggered as part of expected recovery flows,
including intentional fault-injection tests.

Printing this at ERROR level is too noisy and causes false-positive
dmesg-warn failures in CI. Switch the log level to INFO, matching the
adjacent CAT error handler.

wait what?!

If it is fault injection case it is an actual error.
Add instrumentation in the test tool or CI to deal with it.

Sounds sane and matches the CAT error handler.

Could we ratelimit the GUC_ID_UNKNOWN branch too? keeping both paths 
consistent with the CAT handler.
