[PATCH] wer: Fix WER_REOPORT_TYPE failures on recent win10

[Detlef Riekenberg]

Recent win10 (1709 or older) added checks for WER_REPORT_TYPE and reject invalid values
WerReportCreate always succeeded in older dll versions.

Example failures
(full report with 90 failures after upgrading from win7 to win10)
http://test.winehq.org/queue/errksCfJ/report

cw1 (1709):
http://test.winehq.org/data/829170f3d6b875f7a6f065072cc3334a20ff805e/win10_cw1-hd6800-1709-t64/wer:main.html
