In wpa_supplicant_terminate_proc(), while iterating and
terminating interfaces, after an interface is terminated,
we can no longer access its memory as it is no longer valid
and causes a crash.
Fix this by saving the pointer to the next interface before freeing
the current one to avoid accessing an invalid memory location.
