Camera: Fix for main image corruption

Use proper luma offset while registering the snapshot buffer with
kernel. In the present code luma offset is hard coded to 0 when
registering , this holds good only when the image height is a
multiple of 16.But, for the cases where the image height is not
a multiple of 16 and for the jpeg rotation values of 90 and 180,
the luma offset is calculated differently and it becomes a non
zero value.So, use this calculated luma offset value instead
of hard coded 0 when registering the buffer.
