xprtrdma: Update the GFP flags used in xprt_rdma_allocate()
Reflect the more conservative approach used in the socket transport's
version of this transport method. An RPC buffer allocation should
avoid forcing not just FS activity, but any I/O.
In particular, two recent changes missed updating xprtrdma:
- Commit c6c8fe79a83e ("net, sunrpc: suppress allocation warning ...")
- Commit a564b8f03986 ("nfs: enable swap on NFS")
