remove elseif from the lua script

[gurgunday]

We are returning in each case so we don't need the elseif

Can't believe I realized this after it got merged

[Eomm]

Does it mean we don't have a test for it? 😏

[gurgunday]

Haha no no, we do have tests, this change didn't alter Redis's behavior

There are return statements inside the conditional checks, eliminating the need for an else if clause; a return statement would already exit the control flow

So it's just a minor personal preference refactor
