Subject: net/mlx5e: TC, Move kfree() calls after destroying all resources
Patch-mainline: v5.17-rc1
Git-commit: 88d974860412f2ca337086aa25e12b1094d55c6c
References: jsc#PED-1549
When deleting fdb/nic flow rules first release all resources
and then call the kfree() calls instead of sparse them around
the function.
