[Mesa-dev] [st/va] change va max_entrypoints

[Namburu, Chandu-babu]

From: Chandu Babu N <mailto:chandu at amd.com>

As encode support is added along with decode, increase max_entrypoints to two.
vaMaxNumEntrypoints was returning incorrect value and causing 
memory corruption before this commit

v2: assert when max_entrypoints needs to be bigger
