[PATCH v1 2/6] Revert "nl80211: Indicate interface-down event only for the main netdev"

[oleksandr.savchenko at celeno.com]

From: Alexander Savchenko <oleksandr.savchenko at celeno.com>

This reverts commit 106fa1e97e29e7514ae324020802c280f993ee48.

Commit 106fa1e97 breaks the virtual AP mode due to non-main interfaces
can't receive DOWN state.
