drm/xe: Fix Wa_22011802037 annotation

Browse Source 
It was missing one digit, so not showing up as a proper WA number. Add
the missing number and annotate it with a FIXME as there are more to be
implemented to consider this WA done: ensure CS is stop before doing a
reset, wait for pending.

Also, this WA applies to platforms up to graphics version 1270 (with the
exception of MTL A*, that are not supported in xe). Fix platform check.
