drm/qxl: remove set but not used variables 'driver, qbo' 

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/gpu/drm/qxl/qxl_release.c: In function 'qxl_release_fence_buffer_objects':
drivers/gpu/drm/qxl/qxl_release.c:431:17: warning:
 variable 'qbo' set but not used [-Wunused-but-set-variable]

drivers/gpu/drm/qxl/qxl_release.c:430:24: warning:
 variable 'driver' set but not used [-Wunused-but-set-variable]

'qbo' not used since commit f2c24b83ae ("drm/ttm: flip the switch, and convert
to dma_fence")

And 'driver' never used since introduction in
8002db6336 ("qxl: convert qxl driver to proper use for reservations")
