MLK-11881 video: fbdev: mxc ipuv3 fb: Correct ->prefetch in ioctrl SET_PREFETCH
When a framebuffer is blanked, the user may call the MXCFB_SET_PREFETCH ioctrl
to enable or disable the prefetch engine. After sanity check, the cached
->prefetch should reflect the user's intention for next unblank operation
any way instead of checking ->cur_prefetch first.
