Subject: [PATCH] jfs: add setlease file operation

Add the setlease file_operation to jfs_file_operations and
jfs_dir_operations, 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.
