Tomasz Grabiec 1a9d1d380a Reads from cache lack preemption check when scanning over range tombstones ...

A scan over range tombstones will ignore preemption, which may cause
reactor stalls or read failure due to std::bad_alloc.

This is a regression introduced in
5e97fb9fc4.  _lower_bound_changed was
always set to false, which is later checked at preemption point and
inhibits yielding.

Closes #10900
