If some Windows services stop while testing EnumServicesStatusW()'s
resume handle support, one possibility is that the still running
services all fit in the specified buffer, invalidating the test so
there is a retry in place.
But in some cases the second call just returns fewer tests than
expected. So retry in that case too.

Fixes misplaced IME windows.

After allocation the pointer gets shifted by sizeof(xf86vm_modes),
so we have to undo that before calling free.

Fixes crashes running with a null driver.

Commit 100504d2 introduced using GetDpiForWindow().
Unfortunately NOTEPAD_LoadSettingFromRegistry is executed when
the main window is not yet created, resulting in
having Globals.lfFont.lfHeight=0.
This is later stored in the registry in iPointSize=0.

In a fresh wine prefix there are not yet registry values created,
therefore the first run of notepad does not show this problem,
and iPointSize is saved with a sane value to the registry.

Having Globals.lfFont.lfHeight=0 manifests for example
in cups PDF prints being a single empty page.

The check of point_size for having a non-zero value should also fix
wine prefixes which have already a stored registry value of iPointSize=0.
