cfg80211: Userspace may inform kernel of mesh auth method.
Authentication takes place in userspace, but the beacon is
generated in the kernel. Allow userspace to inform the
kernel of the authentication method so the appropriate
mesh config IE can be set prior to beacon generation when
joining the MBSS.
