[Cogl] [PATCH] Fixup for setting point size

[Neil Roberts]

I messed up the comparison in the previous patch so that it would
still try to call glPointSize even if the pipeline has a zero point
size. This was causing GL errors but the conformance tests didn't pick
it up because apparently we haven't been setting
G_DEBUG=fatal-warnings since glib changed a year and a half ago! I'd
like to squash in this change to the patch.
