[Libva] [PATCH v2] va.h: fix compile warning

[Li Zhijian]

If we specify compiling option with "-Werror=strict-prototypes", we
will get the following error:
va/va.h:294:1: error: function declaration isn't a prototype [-Werror=strict-prototypes]
typedef int (*VAPrivFunc)();

This patch declares the VAPrivFunc with parameter 'void', to make the
compiler happy.
