[win32] RP_ShellPropSheetExt_Private::SubtabDlgProc(): Return FALSE instead of calling DefSubclassProc().

Browse Source 
This *usually* didn't cause any problems when using Windows Explorer,
but Directory Opus appears to do its own subclassing. The end result
is Directory Opus crashes when selecting the rom-properties tab in
file properties.

NOTE: Since it's a dialog procedure, it needs to return FALSE instead of
calling DefWindowProc, and definitely not DefDlgProc.

As per MSDN: https://learn.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-defdlgprocw

The **DefDlgProc** function must not be called by a dialog box procedure;
doing so results in recursive execution.

Fixes #405: Crash when used inside Directory Opus
