Revert "anv: flag BO for write combine when CPU visible and potentially in lmem"

Browse source 
This fixes a performance regression between 22.2 and 23.0. A different
fix is present in the main branch, but for 23.0 it was decided to revert
the offending change rather then the more complete fix.

This reverts commit 582bf4d9f7.
