[PATCH] timers: fix offset calculation when the expires align with LVL_GRAN

when the expires of timer is align with LVL_GRAN(n), it will be trigged in 'expires + LVL_GRAN(n)'. Some drivers like power runtime use the timer to start a power down of device, it could saves power if the timer is triggerd in time, especially when LEVEL=0 with low expires. Signed-off-by: Xu
