RFR: 8179227: com/sun/management/OperatingSystemMXBean/TestTotalSwap.java: Expected total swap size ... but getTotalSwapSpaceSize returned ...

The failure is very intermittent and I wasn't able to reproduce it.

I suspect that the swap might be changed during test execution so I add the corresponding check. 

If test still fails after fix we should at least exclude this potential problem.
