net/mlx5e: allocate 'indirection_rqt' buffer dynamically
Increasing the size of the indirection_rqt array from 128 to 256 bytes
pushed the stack usage of the mlx5e_hairpin_fill_rqt_rqns() function
over the warning limit when building with clang and CONFIG_KASAN:
drivers/net/ethernet/mellanox/mlx5/core/en_tc.c:970:1: error: stack frame size of 1180 bytes in function 'mlx5e_tc_add_nic_flow' [-Werror,-Wframe-larger-than=]
Using dynamic allocation here is safe because the caller does the
same, and it reduces the stack usage of the function to just a few
bytes.
