[Mesa-dev] [PATCH] radeonsi: fix invalidating bindless buffer descriptors

[Samuel Pitoiset]

The VA is stored at [4:5], not [0:1]. This invalidated all
texture buffer descriptors when they were made resident in
the current context.

This removes few partial flushes and cache invalidations which
are needed when updating a bindless descriptor on the fly with
a WRITE_DATA packet.
