patch to fix

There is no check in MacLow whether the corresponding EdcaTxopN has TXOP. With the introduction of a new assert in changeset 12451:ac1e0cdd5ca9 (bug 2463), simulation does crash in such scenario. MacLow should only call StartNext if there is a TXOP.
Attached patch is fixing the issue.

This causes 80211e-txop example to fails (see bug 2599).
80211e-txop example should be added to the regression run asap, so I suggest to deliver this fix.
