Subject: Check DTLS_BAD_VER for version number.
Origin: upstream: http://git.openssl.org/gitweb/?p=openssl.git;a=commitdiff_plain;h=9fe4603b8245425a4c46986ed000fca054231253
Bug-Debian: http://bugs.debian.org/701826
Bug: http://rt.openssl.org/Ticket/Display.html?id=2984&user=guest&pass=guest

The version check for DTLS1_VERSION was redundant as
DTLS1_VERSION > TLS1_1_VERSION, however we do need to
check for DTLS1_BAD_VER for compatibility.
