Driver: fix the annoying "Failed to release userptr..." error message
Driver: fix the annoying "Failed to release userptr..." error message

It is a drm related bug. As the drm driver changed the time to free their test
userptr to bufmgr destroy(30921483c70c6939f017476eac13da6aa26b3b3c), we need
anothr order to release our driver to make sure the test userptr can be freed
with a valid fd.
