[PATCH net-next] net: mlx5: Fix compiling error in tls.c

[Mao Wenan]

There are some errors while compiling tls.c if
CONFIG_MLX5_FPGA_TLS is not obvious on.

drivers/net/ethernet/mellanox/mlx5/core/en_accel/tls.c: In function mlx5e_tls_set_ipv4_flow:
./include/linux/mlx5/device.h:61:39: error: invalid application of sizeof to incomplete type struct mlx5_ifc_tls_flow_bits

this patch is to fix this error using 'depends on MLX5_FPGA_TLS' when MLX5_TLS is set.
