hostapd: Fix interface selection for the nl80211 driver
This patch allows the nl80211 driver to create its own per-bss context and pass it to the drv_priv pointer of the hostapd bss state. With this and the following patch, stations can associate to and switch between multiple BSS interfaces of a single wiphy. This obsoletes a few instances of passing ifname to a callback, those can be removed in a separate patch. It might also be useful to move more fields from the driver data to the per-bss data structure in the future.
