net/eth: fix incorrect check of iov_to_buf() return value
So we have sizeof(struct in6_address) != sizeof(uintptr_t) and Clang > Coverity on this, see 4555ca6816c :) net/eth.c:426:30: warning: The code calls sizeof() on a pointer type. This can produce an unexpected result return bytes_read == sizeof(dst_addr); ^ ~~~~~~~~~~ net/eth.c:475:34: warning: The code calls sizeof() on a pointer type.
