IB/mlx5: Fix scatter to CQE in DCT QP creation
When scatter to CQE is enabled on a DCT QP it corrupts the mailbox command
since it tried to treat it as as QP create mailbox command instead of a
DCT create command.
The corrupted mailbox command causes userspace to malfunction as the
device doesn't create the QP as expected.
A new mlx5 capability is exposed to user-space which ensures that it will
not enable the feature on DCT without this fix in the kernel.
