s3: Make sure our CLEAR_IF_FIRST optimization works for the notify tdbs
The notify tdb files are opened at tconX time, which leads to one fcntl lock
for CLEAR_IF_FIRST detection per smbd. This opens the tdbs in the parent and
holds it, so that tdb_reopen_all correctly catches the CLEAR_IF_FIRST bit.
