libobs: Remove extra gs_flush calls

Browse Source 
These calls introduce pipeline stalls in OpenGL on low end machines
which can contribute to a fairly significant 10-30% of total rendering
time.

The driver already needs to synchronize events within the context so
these calls are not needed for correctness for OpenGL.
