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.

Given there is a loop going on here, it would be good to double-check whether
this variable was supposed to be used for something useful or if it was just a
remnant of a version previous to v1.4.
