Revert "persist_data: cache connection and use cursor"
Caching the database connection can cause serious issues if it results in multiple processes (e.g. multiple tasks) simultaneously using the same connection. This reverts commit 8a6876752b90efd81d92f0947bfc9527d8260969. (Bitbake rev: 60b9b18eafad5ac46c7cf1048d749d673c2ee0ad) Signed-off-by: Chris Larson <chris_larson@mentor.com> Signed-off-by: Richard Purdie <rpurdie@linux.intel.com>
