Subject: net/mlx5: Pass a namespace for packet reformat ID allocation
Patch-mainline: v4.20-rc1
Git-commit: 31ca3648f01bf19ae64618521ce539615cc0d5a0
References: bsc#1103990 FATE#326006

Currently we attach packet reformat actions only to the FDB namespace.
In preparation to be able to use that for NIC steering, pass the actual
namespace as a parameter.
