NFSv4.2: fix handling of COPY ERR_OFFLOAD_NO_REQ
If the client sent a synchronous copy and the server replied with ERR_OFFLOAD_NO_REQ indicating that it wants an asynchronous copy instead, the client should retry with asynchronous copy. Fixes: 539f57b3e0fd ("NFS handle COPY ERR_OFFLOAD_NO_REQS") Signed-off-by: Olga Kornievskaia <kolga@netapp.com> Signed-off-by: Anna Schumaker <Anna.Schumaker@Netapp.com>
