net/ice: remove redundant RSS configuration for GTPU

Originally, the default RSS for GTPU is inner fields. Now, we hope outer
RSS for GTPU to be the default.

Since RSS for IPv4, RSS for IPv6, RSS for UDP and RSS for TCP can cover
the cases of outer RSS for GTPU, this patch deletes redundant default
RSS configurations for GTPU.
