fix potential null pointer dereference found by Coverity

CID 355460 (#1 of 1): Dereference before null check (REVERSE_INULL)check_after_deref: Null-checking p suggests that it may be null, but it has already been dereferenced on all paths leading to the check.
737                if (p == NULL)
738                {
739                        return false;
740                }
