org-src: Refactor inline src block fontify lines

* lisp/org-src.el (org-fontify-inline-src-blocks-1): Refactor
`org-fontify-inline-src-blocks-1' to bring down the maximum line
length.  While we're at it, get rid of the debugging `message' call that
somehow made its way in, and an unused variable in the `let' statement.
