8263894: Convert defaultPrinter and printers fields to local variables

[aivanov-jdk]

PrintServiceLookupProvider has defaultPrinter and printers fields but they are used only in getDefaultPrintService() and refreshServices() correspondingly. Thus these two fields can be converted to local variables in the corresponding methods.

Why did you delete the comments ?

The comments highlighted the difference between what is stored in printers and in printServices: excludes vs. includes the default printer. However, according to the code, printers included the default printer too.

Now there's only printServices which contains all print services. I decided the comment didn't have much value now. Yet, upon thinking about it, the comment for printServices still provides additional insight: the array also contains the defaultPrintService.
