[ Upstream commit a16b8e0dcf7043bee46174bed0553cc9e36b63a5 ]
In the cited commit inner_tirs argument was added to create and destroy inner tirs, and no indication was added to mlx5e_modify_tirs_hash() function. In order to have a consistent handling, use inner_indir_tir[0].tirn in tirs destroy/modify function as an indication to whether inner tirs are created. Inner tirs are not created for representors and before this commit, a call to mlx5e_modify_tirs_hash() was sending HW commands to modify non-existent inner tirs.
