[PATCH 1/1] setupapi: Respect ERROR_SHARING_VIOLATION from open KnownDLL file handles.

[William Horvath]

From: William Horvath

create_dest_file was unaware of the FILE_SHARE_READ | FILE_SHARE_DELETE share
mode that these SessionMgr entries are opened with. This avoids noisy
(error=80) messages during prefix creation/update.

Fixes: 81ea1e7a20c9cd0698c0416282d9ad7c0109e865
