QUIC: improved setting the lost timer.
Setting the timer is brought into compliance with quic-recovery-34. Now it's
set from a single function ngx_quic_set_lost_timer() that takes into account
both loss detection and PTO. The following issues are fixed with this change:
- when in loss detection mode, discarding a context could turn off the
timer forever after switching to the PTO mode
- when in loss detection mode, sending a packet resulted in rescheduling the
timer as if it's always in the PTO mode
