IMPALA-3953: Fixes for KuduScanNode BE test failure
After a previous fix for IMPALA-3857, KuduScanNodeTest
TestLimitsAreEnforced (BE test) occasionally throws when a
scanner thread takes a lock_ that isn't valid, crashing the
process.
It looks like the issue is likely that TestScanEmptyString
isn't closing its KuduScanNode, and a lingering
ScannerThread may end up touching invalid memory later.
This fixes the test case and also:
1) Adds some missing synchronization in KuduScanNode which
was found in the process of investigating this issue.
2) Adds a DCHECK on ~KuduScanNode() to ensure it was closed.
This was tested by running KuduScanNodeTest in a loop for 5
hours. Without the fix, the failure was produced within
several hours.
