When adding a RSS rule with GTPU_DWN/UP, it will write from top to
bottom for profile due to firmware limitation. 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 remembering a gtpu_eh RSS
configure and removing it before the corresponding RSS configure
for downlink/uplink rule is issued.
Fixes: 2e2810fc1868 ("net/ice: fix GTPU RSS")

v3:
* Rename global structure.
* Use some macros to avoid code duplication.
* Revise incorrect code where uses local variable.
v2:
* Refine commit log.
* Fix gtpu downlink and uplink can't be issued simultaneously.
* Fix gtpu down/uplink ipv4_udp/tcp or ipv6_udp/tcp symmetric
don't take effect.
