Fix eglCreateImage() from a packed dma_buf surface with a non-zero offset
to pixels data. In particular, this fixes support for planar YUV surfaces
when they are individually mapped on a per-plane basis, i.e. when the
OES_EGL_image_external is not used and user application wants to use its
own shader code for composition, or processing on individual plane (OCL).
