net/sfc: fix memory allocation size for cache

The size of unit cache should be sizeof(**cache) instead of
sizeof(*cache). Memory reallocation is inadequate by sizeof(*cache)
for the platform whose size of pointer is 32-bits. Found by coccinelle
(see https://coccinelle.gitlabpages.inria.fr/website) script.
