Subject: net/mlx5: Fix some error handling paths in 'mlx5e_tc_add_fdb_flow()'
Patch-mainline: v5.16-rc8
Git-commit: 4390c6edc0fb390e699d0f886f45575dfeafeb4b
References: jsc#SLE-19253

All the error handling paths of 'mlx5e_tc_add_fdb_flow()' end to 'err_out'
where 'flow_flag_set(flow, FAILED);' is called.

All but the new error handling paths added by the commits given in the
Fixes tag below.

Fix these error handling paths and branch to 'err_out'.

Fixes: 166f431ec6be ("net/mlx5e: Add indirect tc offload of ovs internal port")
Fixes: b16eb3c81fe2 ("net/mlx5: Support internal port as decap route device")
