nvme/rdma: clear dif_enable when rdma_req is free

Browse Source 
The dif_enable is not cleared in _nvmf_rdma_request_free. When the
rdma_req is used again, the dif_enable is true while
dif.dif_ctx->block_size is zero. As a result, an infinite loop occurs in
nvmf_rdma_fill_wr_sgl.

Fix issue: #2380
