This fixes the DRM_IOCTL_MODE_GETFB ioctl for cirrus so that it returns an actual handle instead of failing with ENODEV.
Tested in a QEMU VM with "-vga cirrus" by running this script: https://chromium.googlesource.com/chromiumos/third_party/autotest/+/master/client/bin/screenshot.py Implementation cargo-culted from radeon_user_framebuffer_create_handle().
