SUNRPC: Remove unreachable error condition 

rpc_clnt_test_and_add_xprt() invokes rpc_call_null_helper(), which
return the value of rpc_run_task() to "task". Since rpc_run_task() is
impossible to return an ERR pointer, there is no need to add the
IS_ERR() condition on "task" here. So we need to remove it.

Fixes: 7f55489058 ("SUNRPC: Allow addition of new transports to a struct rpc_clnt")
