Bug description:
  While testing Bionic daily build with kernel 4.15.0-20-generic we saw
  the following issue with the KVP daemon:

  KVP daemon crashes after approximatively 2 minutes of uptime and it enters in 
a failed state. The daemon can be manually started and it enters back in active 
(running) state.
  The error messages from /var/log/syslog after the daemon enters the failed 
state are the following:

  Apr 25 04:28:46 bionicDaily KVP: read failed; error:9 Bad file descriptor
  Apr 25 04:28:46 bionicDaily systemd[1]: hv-kvp-daemon.service: Main process 
exited, code=exited, status=1/FAILURE
  Apr 25 04:28:46 bionicDaily systemd[1]: hv-kvp-daemon.service: Failed with 
result 'exit-code'.
  Apr 25 04:28:59 bionicDaily systemd[1]: Started Hyper-V KVP Protocol Daemon.
