[PATCH 11/24] jffs2: add setlease file operation

[Jeff Layton]

Add the setlease file_operation to jffs2_file_operations and
jffs2_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.
