RDMA/core: Fix ib_dma_max_seg_size()
commit ecdfdfdbe4d4c74029f2b416b7ee6d0aeb56364a upstream.
If dev->dma_device->params == NULL then the maximum DMA segment size is 64
KB. See also the dma_get_max_seg_size() implementation. This patch fixes
the following kernel warning:
DMA-API: infiniband rxe0: mapping sg segment longer than device claims to support [len=126976] [max=65536]
