Fix OpenSSL build

Commit 04d713f8f ("Add openconnect_set_loglevel()") changed the name of
the vpninfo argument to the vpn_progress() macro from 'vpninfo' to '_v'
to make it more readable. I missed one usage of it, which still actually
worked everywhere except in the OpenSSL ui_progress() where it *isn't*
being used with a local variable called 'vpninfo'.
