[VDPAU] [PATCH] vdpauinfo: remove is_supported initializers

[Aaron Plattner]

These variables were initialized to work around a bug in the NVIDIA driver where
the is_supported output parameter was only initialized if the feature being
queried was not supported.  This was fixed in the 190.* driver release series,
making the workaround unnecessary.
