SUNRPC: Report network/connection errors correctly for SOFTCONN rpc tasks
In the case of a SOFTCONN rpc task, we really want to ensure that it reports errors like ENETUNREACH back to the caller. Currently, only some of these errors are being reported back (connect errors are not), and they are being converted by the RPC layer into EIO.
