When adding a RSS rule with GTPU_DWN/UP, it will search profile
table from the top index. If a RSS rule with GTPU_EH already exists,
then GTPU_DWN/UP packet will match GTPU_EH profile. This patch solves
this issue by removing existed GTPU_EH rule before creating a new
GTPU_DWN/UP rule.

Fixes: 2e2810fc1868 ("net/ice: fix GTPU RSS")
