net/mlx5: Accumulate levels for chains prio namespaces
Tc chains are implemented by creating a chained prio steering type, and
inside it there is a namespace for each chain (FDB_TC_MAX_CHAINS). Each
of those has a list of priorities.
Currently, all namespaces in a prio start at the parent prio level.
But since we can jump from chain (namespace) to another chain in the
same prio, we need the levels for higher chains to be higher as well.
So we created unused prios to account for levels in previous namespaces.
Fix that by accumulating the namespaces levels if we are inside a chained
type prio, and removing the unused prios.
Fixes: 328edb499f99 ('net/mlx5: Split FDB fast path prio to multiple namespaces')
