staging: vboxvideo: Fix reporting invalid suggested-offset-properties
The x and y hints receives from the host are unsigned 32 bit integers and
they get set to -1 (0xffffffff) when invalid. Before this commit the
vboxvideo driver was storing them in an u16 causing the -1 to be truncated
to 65535 which, once reported to userspace, was breaking gnome 3.26+
in Wayland mode.
This commit stores the host values in 32 bit variables, removing the
truncation and checks for -1, replacing it with 0 as -1 is not a valid
suggested-offset-property value. Likewise the properties are now
initialized to 0 instead of -1, since -1 is not a valid value.
This fixes gnome 3.26+ in Wayland mode not working with the vboxvideo
driver.
