<AWT Dev> RFR: 8272342: [TEST_BUG] java/awt/print/PrinterJob/PageDialogMarginTest.java catches all exceptions

[rajat mahajan]

Removed try catch block so the test can function as expected and fail
when it ought to, rather than passing all the time because of catch
block catching all exceptions and Passing test even there is a failure.
