When writing to a depth texture the driver is first doing a decompress
blit to a stageing resource. On one hand this blit can be skipped, if
PIPE_MAP_DISCARD_WHOLE_RESOURCE is set, OTOH we need to clear the
PIPE_MAP_UNSYNCHRONIZED flag if a partial write is done, because we have to
wait until the blit is finished.

v2: Update the patch with a more targeted approach.

Fixes: 25b97a3a96 ("mesa/st: mark internal texture map calls as UNSYNCHRONIZED")
Closes: https://gitlab.freedesktop.org/mesa/mesa/-/issues/13916
