From: Eliad Peller <eliad@wizery.com>

wpa_ctrl_command_sta(), called by the "ALL_STA" handler,
didn't consider ifname_prefix, resulting in various
commands being sent to the global control interface,
rather than the specified interface.

This in turn caused the unexpected "UNKNOWN COMMAND"
result be considered as valid station, resulting in
infinite loop while trying to get all stations.

Fix it by considering ifname_prefix, similarly
to _wpa_ctrl_command().
