SBE: Account cancelled timer request
[ Upstream commit b44c7594523d20945179e497c45ec9007981ac75 ]
Currently we are not accounting cancelled timer request. So in some
corner cases we may schedule new timer request with
new-timer-value > inflight-timer-value.
Lets explicit check new_target value with inflight timer value.
