[Libva] libva memory leak

[Shuang He]

The basic idea is let valgrind know what memory we have allocated via 
special ioctl, by using following valgrind APIs:
     VALGRIND_MALLOCLIKE_BLOCK()
     VALGRIND_FREELIKE_BLOCK()
That patch haven't been updated for a long while, attached for your 
reference

Thanks
