netdev: Fix an use of uninitialized mutex.

Commit 05bf6d3c62e1d (ovs-thread: Add checking for mutex and
rwlock initialization.) helps find an use of uninitialized
mutex (netdev_class_mutex) during upgrade.  The assertion
check aborts the ovs.

This commit fixes the issue by adding the proper initialization.

Bug #1239914.
Bug #1240598.
