i915: Avoid mis-counting vblank interrupts when they're only enabled for pipe A.
It looks like 'after a while', I915REG_INT_IDENTITY_R for some reason always has VSYNC_PIPEB_FLAG set in the interrupt handler, even though pipe B is disabled. So we only increase dev->vbl_received if the corresponding bit is also set in dev->vblank_pipe. (cherry picked from 881ba569929ceafd42e3c86228b0172099083d1d commit)
