For Periodic timers ,if the lag gets introduced, the current code 
added additional delay when the next peridoc timer was initialized 
by not taking into account the delay added, with this fix the code 
would start the next occurrence of timer keeping in account the 
lag added.Corrected the behavior.

Fixes:rte_timer: timer lag issue
