I hit a build warning when building the net selftests.
gro.c: In function 'check_capacity_pkts': gro.c:1249:13: warning: variable 'total_data' set but not used [-Wunused-but-set-variable=]
1249 | int total_data = 0;
| ^~~~~~~~~~
Remove the total_data variable, as it is no longer used.
Fixes: d97348474708 ("selftests: drv-net: gro: always wait for FIN in the capacity test")
