Do not return non-nil *lisafs.Inode to doCreateAt on error.
lisafs.ClientFile.MkdirAt is allowed to return a non-nil Inode and a non-nil
error on an RPC error. The caller must not use the returned (invalid) Inode on
error. But a code path in the gofer client does end up using it.
More specifically, when the Mkdir RPC fails and we end up creating a synthetic
dentry for a mountpoint, we end up returning the (invalid) non-nil Inode to
filesystem.doCreateAt implementation which thinks that a remote file was
created. But that non-nil Inode is actually invalid because the RPC failed.
Things go downhill from there.
Update client to not use childDirInode if RPC failed.
