Trond Myklebust 321c75b01c NFS/pNFS: Report EINVAL errors from connect() to the server
[ Upstream commit dd7d7ee3ba2a70d12d02defb478790cf57d5b87b ]

With IPv6, connect() can occasionally return EINVAL if a route is
unavailable. If this happens during I/O to a data server, we want to
report it using LAYOUTERROR as an inability to connect.

Fixes: dd52128afdde ("NFSv4.1/pnfs Ensure flexfiles reports all connection related errors")
