Martin Krastev 21fe1069aa drm/vmwgfx: Fix vmw_du_get_cursor_mob fencing of newly-created MOBs
[ Upstream commit ed96cf7ad590989b009d6da5cd26387d995dac13 ]

The fencing of MOB creation used in vmw_du_get_cursor_mob was incompatible
with register-based device communication employed by this routine. As a
result cursor MOB creation was racy, leading to potentially broken/missing
mouse cursor on desktops using CursorMob device feature.
