check_safe_pointers: only report on EXPR_PREOP dereferences.

DEREF_HOOK reports on both: PREOP * and struct . member The form are the dereferences we want. The latter aren't really dereferences at all, just member accesses. Also don't report the leading '*', just the thing being dereferenced. Signed-off-by: NeilBrown <neil@brown.name>
