wifi: iwlwifi: mld: Block EMLSR when scanning on P2P Device

Temporarily block EMLSR when scanning on a P2P Device interface,
as this is an indication that P2P activity is about to start, e.g.,
P2P client connection to a P2P GO.

Since a P2P scan while a station interface connection is active might
be long, increase the EMLSR blocking timeout to 10 seconds.
