[SHELL32] Prevent a second call to Drive Properties dialog (#4888)

[SHELL32] Prevent a second call to Drive Properties dialog (#4888)

CDefaultContextMenu::DoProperties provides a fallback call
to the property sheet testing the return value of the _DoCallback method,
which is ultimately the return value of SH_ShowDriveProperties().

SH_ShowDriveProperties() sometimes returns an HRESULT, however it is marked
as returning a BOOL. Then, DrivesContextMenuCallback() always handles this
result as an HRESULT.

Fix SH_ShowDriveProperties() to always return a BOOL as it is intended,
and in DrivesContextMenuCallback() handle the result accordingly.
