This is caused by upstream commit and happens for interfaces with P2P management interface:

commit 21efc940f6e7f07b84b7e5c5867f3d81594c4fb0
Author: Tomasz Bursztyka <tomasz.bursztyka@linux.intel.com>

wpa_supplicant: Do not register a P2P management interface on DBus

DBus client should always request the proper netdev interface. This will
be necessary to get a consistent behavior whatever driver is in use:
iwlwifi (which requires a P2P mgmt dev), ath9/10k (which does not),
etc...

@Christian: Could you post that information to the upstream mailing list? (If not, I'll try to do that tomorrow.)
