ice: Fix off by one in ice_tc_forward_to_queue()

The > comparison should be >= to prevent reading one element beyond
the end of the array.

The "vsi->num_rxq" is not strictly speaking the number of elements in
the vsi->rxq_map[] array.  The array has "vsi->alloc_rxq" elements and
"vsi->num_rxq" is less than or equal to the number of elements in the
array.  The array is allocated in ice_vsi_alloc_arrays().  It's still
an off by one but it might not access outside the end of the array.
