(once again with the attachment...)

This patch fixes the following problem:

In mdb_cursor_put, section 'put_sub', if the variable dkey.mv_size is non-zero,
then it means dkey contains some original data which has to be put back in the
child db, typically when the child db has just been created.

But when using MDB_MULTIPLE, if this variable has not been resetted to zero, we
may come back to this section and wrongly think that there is some original data
to be taken care of.
