v4l2allocator: fix import_userptr() in single-planar API when n_planes > 1

Yes, I think so, so in this case, I think we should just return in error, at
least for now.
So, here is a new patch proposal to handle the issue and check that planes are
contiguous and have expected size. To do this I used the following idea:
if planes are contiguous and have expected size so plane 'i' start address +
plane 'i' expected size shall be equal to plane 'i + 1' start address.
I think it's enough to do the job, but please tell me if I'm wrong or if I'm
miss
Please tell me if i missed something.
