Ignore unused argument in paredit-override-check-parens-interactively

The resulting byte code is more compact and the only reason it is
being used is to avoid the warning about unused arguments.

(disassemble (lambda (condition) condition nil))

    byte code:
      args: (condition)
    0       varref    condition
    1       discard
    2       constant  nil
    3       return

(disassemble (lambda (condition) (declare ignore condition) nil))

    byte code:
      args: (condition)
    0       constant  nil
    1       return
