nfs: properly disallow delegation requests on directories
Checking for S_ISREG() in nfs4_setlease() is incorrect, since that op is
never called for directories. The right way to deny lease requests on
directories is to set the ->setlease() operation to simple_nosetlease()
in the directory file_operations.
Fixes: e6d28ebc17eb ("filelock: push the S_ISREG check down to ->setlease handlers")
