Subject: Remove redundant check.
X-Git-Tag: v2.0.0rc1~296
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=81ccd50f6033a3e7398dc66e56469e2a71c71c6a;p=thirdparty%2Fdnspython.git

Remove redundant check.

_validate_rrsig will never be called if cryptography wasn't loaded, so
there's no need to check again.
