[Fix](merge-on-write) Fix MergeIndexDeleteBitmapCalculator::calculate_one() coredump

[bobhan1]

What problem does this PR solve?

Problem Summary:

MergeIndexDeleteBitmapCalculatorContext::get_current_key() may return non-OK status when encounter memory allocation failure, which makes MergeIndexDeleteBitmapCalculatorContext::Comparator::operator() returns incorrect result and break some assumptions during the process of multiway merging, which leads to coredump.
