Subject: kABI workaround for cfg80211 mgmt_registration_lock changes
Patch-mainline: Never, kABI workaround
References: git-fixes

The recent fix patch
  patches.suse/cfg80211-fix-management-registrations-locking.patch
moved the mgmt_registrations_lock from struct wireless_dev to
struct cfg80211_registered_device, and it caused kABI breakage.
Restore the old spinlock as a placeholder.
