[lldp]: ensure the LLDP PDU is sent immediately when the tx-interval is modified. (#3705)

Browse Source 
When LLDP parameter tx-interval value is modified, there was no immediate PDU sent to peer to update the peer with the latest values. Due to this the update on peer happened only after the next PDU is sent which can cause a delay of upto 30 secs (default value).
