net/mlx5e: fix double free in mlx5e_destroy_flow_table

Browse source

[ Upstream commit 884abe45a9 ]

In function accel_fs_tcp_create_groups(), when the ft->g memory is
successfully allocated but the 'in' memory fails to be allocated, the
memory pointed to by ft->g is released once. And in function
accel_fs_tcp_create_table, mlx5e_destroy_flow_table is called to release
the memory pointed to by ft->g again. This will cause double free problem.
