Reset normal_scans counter upon entering INTERFACE_DISABLED state

Depending on the implementation, the scheduled scan may not give results
quickly when in DISCONNECTED state. This patch resets
wpa_s::normal_scans upon entering to the INTERFACE_DISABLED state so a
normal scan is assured upon going to DISCONNECTED state after the
interface has been re-enabled. This mainly solves a long reconnect time
observed upon repeated kernel driver reloads, i.e., third reload
resulted in a scheduled scan.
