Subject: [PATCH] Update svr-chansession for build issue

Following issue "Compilation error when disabling pubkey authentication (DROPBEAR_SVR_PUBKEY_AUTH)" from davidbernard04, code is modified to take in account that requesting information from method "ses.authstate.pubkey_info" isn't possible since the method is disabled when DROPBEAR_SVR_PUBKEY_OPTIONS_BUILT value is 0.
