RDMA/mlx5: Remove obsolete 32-bit DMA mask fallback
The DMA API guarantees support for masks of 32 bits or wider and
explicitly identifies retrying a 32-bit mask after a 64-bit request as
incorrect:
https://docs.kernel.org/core-api/dma-api-howto.html#dma-addressing-capabilities
Remove the obsolete fallback from data direct while retaining the error
check so that a genuine DMA setup failure is still reported and aborts
initialization.
