Subject: Fix stale sub-cursor C_INIT flag
X-Git-Tag: accepted/tizen/5.0/unified/20181102.030725~608
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=56a41d87d42568328413f6e2a6197c2ae0dc67bd;p=platform%2Fupstream%2Flmdb.git

Fix stale sub-cursor C_INIT flag

Whenever we enter cursor_set() the sub-cursor's flag must be
cleared. If the new cursor position has valid subdata it will
be initialized again, if not then the sub-cursor has nothing
to point to.
