[ Upstream commit acdc3e47881d86dc1cb89d4603e3fed90ab150db ]
Right now, we assign the link address only after we add the link to the driver, which is quite obviously wrong. It happens to work in many cases because it gets updated immediately, and then link_conf updates may update it, but it's clearly not really right.
Set the link address during ieee80211_mgd_setup_link() so it's set before telling the driver about the link.
