This IS_ERR() check was deleted during in a cleanup because, at the time,
the rpcb_call_async() function could not return an error pointer. That
changed in commit
25cf32ad5dba ("SUNRPC: Handle allocation failure in
rpc_new_task()") and now it can return an error pointer. Put the check
back.
A related revert was done in commit
13bd90141804 ("Revert "SUNRPC:
Remove unreachable error condition"").
Fixes: 037e910b52b0 ("SUNRPC: Remove unreachable error condition in rpcb_getport_async()")
