Subject: m_option: fix -vo opengl lscale validation

OPT_STRING_VALIDATE actually did nothing. This made -vo opengl crash or
misbehave when passing an invalid value for the lscale, cscale or 3dlut-
size (the only users for this option type).

The code added with this commit was either blatantly forgotten with the
commit introducing this option type, or somehow lost.
