Fix start of reauthentication after failed authentication with
passthrough (external AAA server) to use internal EAP Identity method.

This reverts commit 204dd3f420.
start_reauth was not supposed to be used in this way and setting it
to TRUE in INITIALIZE breaks internal EAP server.

Previously, sm->start_reauth was set to TRUE in SUCCESS2 state to force
reauthentication to start with EAP identity request. This works fine for
the case of EAP success through the AAA passthrough authentication, but
is not enough to handle passthrough authentication failure. sm->identity
is set in that case and getDecision would return PASSTHROUGH instead of
CONTINUE (to Identity method).

This avoid incorrect errors from some static analyzers that do not like
memmove with pointers just after the end of a buffer even if the number
of bytes to move is zero.

Windows 7 uses incorrect way of figuring out AP's WPS capabilities by
acting as a Registrar and using M1 from the AP. The config methods
attribute in that message is supposed to indicate only the configuration
method supported by the AP in Enrollee role, i.e., to add an external
Registrar. For that case, PBC shall not be used and as such, the
PushButton config method is removed from M1 by default. If pbc_in_m1=1
is included in the configuration file, the PushButton config method is
left in M1 (if included in config_methods parameter) to allow Windows 7
to use PBC instead of PIN (e.g., from a label in the AP).
Commit c3fc47ea8e fixed EAP passthrough
server to allow Logoff/Re-authentication to be used. However, it
broke EAP standalone server while doing that. Fix this by reverting
the earlier fix and by clearing the EAP Identity information in the
EAP server code whenever an EAPOL-Start or EAPOL-Logoff packet is
received.
Some sequencies of EAPOL logoff/logon/start messages seem to be
able to get the previous implementation into state where hostapd
would not be able to start reauthentication when external
authentication server is used. The EAP server code would bypass
the initial Identity Request generation and EAPOL code would not
be able to send anything to the authentication server or supplicant
at that point. Work around this by forcing EAP server code to
start with Identity Request after INITIALIZE state even if the
Identity is known.
