Please just remove model attribute from the record of the workflow.transition as like below.

<record id="workflow_transition_act_done_to_act_cancel" model="workflow.transition">
            <field name="signal">cancel_sheet</field>
            <field name="act_from" ref="hr_payroll.act_done"/>
            <field name="act_to" ref="hr_payroll.act_cancel"/>
            <field name="condition">True</field>        

By this way your issue will resolve and you get the result as you want.

Thanks Emipro its working fine....
