iio:trigger: rename try_reenable() to reenable() plus return void
As we no longer support a try again if we cannot reenable the trigger rename the function to reflect this. Also we don't do anything with the value returned so stop it returning anything. For the few drivers that didn't already print an error message in this patch, add such a print.
