patch 9.0.2118: [security]: avoid double-free in get_style_font_variants
Problem: [security]: avoid double-free
Solution: Only fee plain_font, when it is not the same as bold_font
When plain_font == bold_font and bold_font is not NULL, we may end up
trying to free bold_font again, which already has been freed a few lines
above.
So only free bold_font, when the condition gui.font_can_bold is true,
which means that bold_font is not pointing to plain_font (so it needs to
be freed separately).
