Andrew Cooper 42db2deb5e tools/libxs: Fix length check in xs_talkv() ...

If the sum of iov element lengths overflows, the XENSTORE_PAYLOAD_MAX can
pass, after which we'll write 4G of data with a good-looking length field, and
the remainder of the payload will be interpreted as subsequent commands.

Check each iov element length for XENSTORE_PAYLOAD_MAX before accmulating it.
