pimd: IGMPv2 query timer gets delayed in a scenario

Browse Source 
Problem Statement:
==================
IGMP query is sent at irregular intervals
(more than 30 seconds) when "ip igmp query-max-response-time 100"
command is executed multiple times.

RCA:
=================
When "ip igmp query-max-response-time 100" is executed, the timers
are reset resulting in the delay of sending the query.

Fix:
=================
When there is no change in the config value, we should not reset
the timers.
