[SRU][jammy][PATCH 1/1] net/mlx5e: Set action fwd flag when parsing tc action goto

[John Cabaj]

From: Roi Dayan <roid at nvidia.com>

BugLink: https://canonical.lightning.force.com/lightning/r/Case/5004K00000TKB4OQAX/view (Pickup upstream mlx patch to Ubuntu 22.04 ibm-gt kernel)

Do it when parsing like in other actions instead of when
checking if goto is supported in current scenario.
