Dag Wieers 487cf0ee8d Improve convert_bool error message
The error message as it was confused me when the value was 'enabled' and
there was also a module parameter named 'enabled'.

    enabled is not a valid boolean.  Valid booleans include: yes, on, 1, true, ...

So by clearly describing it as a value, the confusion would have been
avoided.

    The value 'enabled' is not a valid boolean.  Valid booleans include: yes, on, 1, true, ...
