drm/xe/vram: Check disable_vram_page_offline policy in fault handler

Browse source

Before reserving a page at a faulting address, check the cached
disable_vram_page_offline policy from xe->ras. If the policy is
enabled (logging only), log the corrupted address and return
-EOPNOTSUPP so that RAS can report to firmware to drop the
address from the SRAM queue without attempting to offline the
page.
