ovsdb-idl: Fix iteration over rows in IDL tables.
The IDL was returning rows that had existed in the database and were
deleted by the current transaction (that is, row->old && !row->new).
This commit fixes the problem.
The condition used by next_real_row() was just blatantly wrong and
illogical. The correct condition is row->new != NULL. The old condition
only got one case wrong (the one mentioned above), even though it didn't
make much sense.
This fixes an ovs-vsctl call that assert-failed in a "set" command that
iterated through a table from which a previous ovs-vsctl command (in the
same invocation) had deleted a row.
