msm: isp: update logic to reject invalid frame

Frame request should only be accepted between SOF and EOF,
otherwise pingpong buffer will be switched before VFE configure
the correct buffer, which causes pingpong mismatch. Rejecting
all the request after EOF will make sure pingpong buffers are
written correctly and hardware have enough time to be configured.
Use a bool value to indicate if vfe is in correct region to
accept frame request. Set this value at SOF irq and reset it
at EOF irq.
