gl_stream_buffer: Use InvalidateBufferData instead unmap and map

Browse source 
Making the stream buffer resident increases GPU usage significantly on
some games. This seems to be addressed invalidating the stream buffer
with InvalidateBufferData instead of using a Unmap + Map (with
invalidation flags).
