[PATCH 3/6] 9p: don't allow delegations to be set on directories

[Jeff Layton]

With the advent of directory leases, it's necessary to set the
->setlease() handler in directory file_operations to properly deny them.

Fixes: e6d28ebc17eb ("filelock: push the S_ISREG check down to ->setlease handlers")
