[PATCH] wireless: Add ifname to STOP_AP event.

[greearb@candelatech.com]

From: Ben Greear <greearb@candelatech.com>

In case user-space wants to know the name of the
device, this will save a name lookup by index, and
in case where kernel manages to fully delete the
interface before user-space can determine the name,
this will ensure user-space has proper name.
