[PATCH v2 08/29] staging: wilc1000: change return type to 'void' tcp ack filter functions

[Ajay Singh <ajay.kathat@xxxxxxxxxxxxx>]

Use 'void' return type for below functions as they always return '0' and
their return value is not used by caller.
add_tcp_pending_ack()
update_tcp_session()
add_tcp_pending_ack()
