#!/bin/bash
case "$1" in
thaw|resume)
nmcli nm sleep false
pkill -f wpa_supplicant
;;
*)
;;
esac
exit $?

cat /etc/pm/config.d/config

SUSPEND_MODULES="ath10k_pci"

I found a solution finally! Just make this script to remove the module before suspend and reload after.

I used Owais Lone's answer to a similar question to enable automatic resume of wifi after suspension for my laptop (a Dell Precision) on 16.04 LTS.

Like Owais, I created /etc/pm/sleep.d/10_resume_wifi:

#!/bin/sh

case "${1}" in
    resume|thaw)
      nmcli radio wifi off && nmcli radio wifi on;;
esac

followed by a sudo chmod +x /etc/pm/sleep.d/10_resume_wifi.

In case you're wondering about the double semicolons or the solitary close parenthesis like I was, see http://tldp.org/LDP/Bash-Beginners-Guide/html/sect_07_03.html -- that's just how the case syntax works.
