mlx5_st_alloc_index() allocates an mlx5_st_idx_data object for
each new steering tag table index and stores it in the xarray.
When the last user releases the index, mlx5_st_dealloc_index()
removes the entry from the xarray but did not free the backing
object, leaking memory.
Free idx_data after erasing the xarray entry once the refcount
reaches zero.
