[PATCH 1/4] msi: Move parameter checks to a common helper in MsiSummaryInfoSetProperty.

[Dmitry Timoshkov]

Currently MsiSummaryInfoSetProperty tests don't have a chance to execute under
Wine because the tests crash earlier, and the crashes are hidden by a custom
action exception handler. This patch simplifies the next one.
