lints: move misplaced docstring for LINT_VAR_RUN

I guess this got misplaced somewhere along the way while reorganizing
the lint code, but I just now noticed it while browsing the code.

Also removed bit about "if it does not exist error", because that's
not accurate with the present behavior of the lint.
