net/mlx5: fix single not inline packet storing

Browse Source 
The mlx5 PMD can inline packet data into transmitting descriptor (WQE)
and free mbuf immediately as data no longer needed, for non-inline
packets the mbuf pointer should be stored in elts array for coming
freeing on send completion. There was an optimization on storing
pointers in batch and there was missed storing mbuf for single
packet if non-inline was explicitly requested by flag.
