Returns expected SBC after completion of swap to caller, as required by
OML_sync_control spec, instead of the last_swap_target value.
Passes target_msc, divisor, remainder, correctly for
glXSwapBuffersMscOML() call, while retaining old behaviour for simple
glXSwapBuffers() call.
An OML swap can have a 0 target_msc, which just means it needs to
satisfy the divisor/remainder equation. Pass this down to the driver as
needed so we can support it.
