gamemode-context: Avoid `GameModeClient *cl` being NULL

There's no need in defining it at the top of the function. During
rebase, I had one `if` accessing `cl->executable` too early but we were
only storing the path in `executable` at that point.

This change avoids accessing `cl` while it might be NULL.
