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") Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Anna Schumaker <Anna.Schumaker@Netapp.com>
