Add the setlease file_operation to ocfs2_fops, ocfs2_dops,
ocfs2_fops_no_plocks, and ocfs2_dops_no_plocks, pointing to
generic_setlease.  A future patch will change the default behavior to
reject lease attempts with -EINVAL when there is no setlease file
operation defined. Add generic_setlease to retain the ability to set
leases on this filesystem.
