crimson/seastore: fix assert in read_extent

lba btree root leaf is empty after osd reboot, because SegmentStateTracker's states are wrong.
and that is caused by tracker->do_write not finished then seastore closed.

in transaction manager read_extent, can't read extent.
ceph_assert(0 == "Should be impossible");
