Alexander Usyskin 761fb68292 mei: protect mei_cl_mtu from null dereference ... commit bcbc0b2e27 upstream. A receive callback is queued while the client is still connected but can still be called after the client was disconnected. Upon disconnect cl->me_cl is set to NULL, hence we need to check that ME client is not-NULL in mei_cl_mtu to avoid null dereference.
