drm/radeon/r600_cs: clean up of dead code in r600_cs

[ Upstream commit 260dcf5b06d519bcf27a5dfdb5c626821a55c170 ]

GCC 16 enables -Werror=unused-but-set-variable= which results in build
error with the following message.

drivers/gpu/drm/radeon/r600_cs.c: In function ‘r600_texture_size’:
drivers/gpu/drm/radeon/r600_cs.c:1411:29: error: variable ‘level’ set but not used [-Werror=unused-but-set-variable=]
 1411 |         unsigned offset, i, level;
      |                             ^~~~~
cc1: all warnings being treated as errors
make[6]: *** [scripts/Makefile.build:287: drivers/gpu/drm/radeon/r600_cs.o] Error 1

level although is set, but in never used in the function
r600_texture_size. Thus resulting in dead code and this error getting
triggered.
