net/mlx5: fix the profile check of meter mark
Checks
Commit Message
When creating a meter_mark action, the profile should be specified.
Or else there would be a crash if the pointer to the profile was not
set properly:
1. creating an action template with only action mask set and using
this template to create a table
2. creating a flow rule without setting the profile if the action
of meter_mark is not fixed
The check should be done inside the action allocation and an error
needs to be returned immediately.
Fixes: 48fbb0e93d06 ("net/mlx5: support flow meter mark indirect action with HWS")
