completion/wpscan: simplify code flow (whitespace)

[gaelicWizard]

Description

Convert from indented if-block to return then unindented code. This should have basically one line change at the top, one line removed at the bottom, and then all whitespace.

Motivation and Context

Just cleaning up.

Confirmed mostly just the early bailout, whitespace adjustments.

BUT also fixing array to be an actual array.

cc: @tbhaxor I think you and I broke this in #1898 where $_opt_ became the entire OPTS string ...

I'm going tentatively mark as approved but would like @tbhaxor to chime in before merging ...

I've rebased on current master, and changed " to ' for the $OPTS array.
