Sebastien Dugue 12a5a0e39b mlx4_core: Fix possible chunk sg list overflow in mlx4_alloc_icm() 
commit c0dc72bad9 upstream.

If the number of sg entries in the ICM chunk reaches MLX4_ICM_CHUNK_LEN,
we must set chunk to NULL even for coherent mappings so that the next
time through the loop will allocate another chunk.  Otherwise we'll
overflow the sg list the next time through the loop.  This will lead to
memory corruption if this case is hit.

mthca does not have this bug.
