s3:smbd/close remove filesystem lock before removing sharemode
otherwise we are open for a race condition:
opener 1 opens file and closes it
- during the close, the share mode entry will be removed from
locking.tdb, but share mode in the file system will be dropped later
after delete_on_close and write time updates have been done
opener 2 requests open of same file with file overwrite
- locking.tdb does not list original entry, but file system share mode
is still around
- VFS_FTRUNCATE will fail and error was converted to STATUS_ACCESS_DENIED
