overlayfs: add setlease file operation

Browse source

Add the setlease file_operation to ovl_file_operations and
ovl_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.
