commit 5b0bb12c58ac7d22e05b5bfdaa30a116c8c32e32 upstream.
When mlx5_create_flow_group() fails, ft->g should be
freed just like when kvzalloc() fails. The caller of
mlx5e_create_l2_table_groups() does not catch this
issue on failure, which leads to memleak.
Fixes: 33cfaaa8f36f ("net/mlx5e: Split the main flow steering table")
