dpif-netdev: Retrieve dpif_class from struct dp_netdev.
In case a pmd pointer (struct dp_netdev_pmd_thread *) needs to retrieve
the dpif_class it points at - it can access it as: pmd->dp->class. A
second option is to access it as: pmd->dp->dpif->dpif_class. The first
option is safe since there is one dp netdev with a constant pointer to
the dpif class. The second option is not safe since the pointer
pmd->dp->dpif may be changed under the hood, for example, in case there
is a call to dpif_open(). One such scenario is when a netdev bridge is
running while dumping flows statistics with dpctl in parallel:
ovs-appctl dpctl/dump-flows. This commit makes usage of the first
safe option instead of the second option.
