IMPALA-12784: Fix bug in ScanNode.getFilteredInputCardinality
IMPALA-12018 adds method ScanNode.getFilteredInputCardinality(), which
is intended to return filteredInputCardinality_ if it set, but
mistakenly return filteredCardinality_ instead.
filteredInputCardinality_ is only affected by partition runtime filter
or runtime filter pushed to Kudu. On the other hand,
filteredCardinality_ is affected by all runtime filter consumed by a
ScanNode. This patch fixes the bug.
This patch also adds TRACE log at the end of
ScanNode.reduceCardinalityByRuntimeFilter()
Testing:
- Pass FE tests.
