[ backported from upstream commit cd230a3ed985894efafe326cbbf5db7f9e45b25c ]
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.
Fixes: 43e9d9794cde ("net/mlx5: support upstream rdma-core")
