Clang 14 in an (essentially) defconfig loongarch64 build for next-20240327
reports [1]:
drivers/gpu/drm/qxl/qxl_ioctl.c:148:14: error: variable 'num_relocs'
set but not used [-Werror,-Wunused-but-set-variable]
The variable was originally used in the `out_free_bos` label, but commit
74d9a6335dce ("drm/qxl: Simplify cleaning qxl processing command")
removed the use that happened in that label.
Thus remove the unused variable.
Fixes: 74d9a6335dce ("drm/qxl: Simplify cleaning qxl processing command")
Closes: https://lore.kernel.org/lkml/CANiq72kqqQfUxLkHJYqeBAhpc6YcX7bfR96gmmbF=j8hEOykqw@xxxxxxxxxxxxxx/ [1]
