drm/qxl: remove unused count variable from qxl_surface_id_alloc()

Browse Source 
Clang 14 in an (essentially) defconfig loongarch64 build for next-20240326
reports [1]:

    drivers/gpu/drm/qxl/qxl_cmd.c:424:6: error: variable 'count' set
    but not used [-Werror,-Wunused-but-set-variable]

The variable is already unused in the version that got into the tree.

Thus remove the unused variable.
