net/mlx5: fix buffer split offload advertising

Browse Source 
The buffer split Rx offload is not compatible with Multi-Packet
Receiving Queue (MPRQ) Rx offload, hence, the buffer split
offload flag RTE_ETH_RX_OFFLOAD_BUFFER_SPLIT and other related
values should be advertised only if there is no MPRQ engaged.

Fixes: 6c8f7f1c18 ("net/mlx5: report Rx buffer split capabilities")
