media: intel-ipu3: cio2: fix a crash with out-of-bounds access
When dmabuf is used for BLOB type frame, the frame
buffers allocated by gralloc will hold more pages
than the valid frame data due to height alignment.
In this case, the page numbers in sg list could exceed the
FBPT upper limit value - max_lops(8)*1024 to cause crash.
Limit the LOP access to the valid data length
to avoid FBPT sub-entries overflow.
