ENGR00293132-2 pxp/v4l2: restore smem_start for framebuffer even exit abnormally

Previously, the framebuffer for UI display may only be restored after
STREAMOFF ioctl is called. But sometimes the application may exit abnormally
(without call STREAMOFF) for some reason. Now restore previously-saved
smem_start in release function to make sure it's set correctly, to avoid some
video frame remain.
