netlink: Bypass refcounting when setting promiscuityHEADmain

When asking for IFF_PROMISC when modifying interfaces with netlink, set
permanent flag instead (IFF_PPROMISC) as netlink interface modification
has no way of doing promiscuity reference counting through ifpromisc().
We can't do reference counting because every netlink interface
modification necessarily either sets or unsets IFF_PROMISC in ifi_flags,
and ifi_change is usually set to 0xFFFFFFFF.

This logic was the same between this and SIOCSIFFLAGS, so factor out
if_setppromisc() function.
