rpc_pipe: don't overdo directory locking

Don't try to hold directories locked more than VFS requires;
lock just before getting a child to be made positive (using
simple_start_creating()) and unlock as soon as the child is
created.  There's no benefit in keeping the parent locked
while populating the child - it won't stop dcache lookups anyway.
