Documentation/driver-api/cxl: remove page-allocator quirk section
The node/zone quirk section of the cxl documentation is incorrect.
The actual reason for fallback allocation misbehavior in the
described configuration is due to a kswapd/reclaim thrashing scenario
fixed by the linked patch. Remove this section.
