[RFC] fix -Wdiscarded-qualifiers warning

[N-R-K]

Hi, I looked into this because of the following warning:

istream.c:447:20: warning: assignment discards 'const' qualifier from pointer target type [-Wdiscarded-qualifiers]
  447 |             method = X509V3_EXT_get(ex);
      |                    ^

Simply adding const to method seems to compile fine, but it looks like that the pointer isn't even being used. So I'm not sure what's going on here, so my patch is possibly incorrect. Would appreciate if someone can take a look here.

In my local version I have removed method. Running this version since 2021-09-02 without problems.

Looks like @rkta fixed this on #222. Closing this.
