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 line format is not corerct. Fixes line should contain commit hash that introduced the bug and its subject line. For your case below should be added.
Fixes: 9b15ba89 ("timer: use a skip list")
