Johannes Berg 4fa029fc35 nl80211: fix null-ptr dereference on invalid mesh configuration 
commit 265698d7e6132a2d41471135534f4f36ad15b09c upstream.

If TX rates are specified during mesh join, the channel must
also be specified. Check the channel pointer to avoid a null
pointer dereference if it isn't.

Reported-by: Jouni Malinen <j@w1.fi>
Fixes: 8564e38206de ("cfg80211: add checks for beacon rate, extend to mesh")
