Andrea Parri (Microsoft) 71abb94ff6 hv_sock: Check hv_pkt_iter_first_raw()'s return value

The function returns NULL if the ring buffer doesn't contain enough
readable bytes to constitute a packet descriptor.  The ring buffer's
write_index is in memory which is shared with the Hyper-V host, an
erroneous or malicious host could thus change its value and overturn
the result of hvs_stream_has_data().
