net/mlx5: fix CRC strip capability query

IBV_WQ_FLAGS_SCATTER_FCS is a WQ flag to be used to configure the CRC
strip on a queue upon creation.

Using IBV_RAW_PACKET_CAP_SCATTER_FCS instead to query to capability.
Even though this is RAW_QP capability, it is being used by rdma-core to
indicate for both RAW_QP and WQ.
