crypto: omap - Allocate OMAP_CRYPTO_FORCE_COPY scatterlists correctly 

commit 1562b1fb7e17c1b3addb15e125c718b2be7f5512 upstream.

The existing allocation of scatterlists in omap_crypto_copy_sg_lists()
was allocating an array of scatterlist pointers, not scatterlist objects,
resulting in a 4x too small allocation.

Use sizeof(*new_sg) to get the correct object size.
