dmesg output, lspci -vv, modinfo ath10k_pci

Description of problem:
After a certain time running (probably every several hours), the ath10k_pci driver crashes and the wireless device stops working. Setting wlan to off and on again will make it work again. This bug was first seen since the last kernel upgrade (from 4.15.9 to 4.15.10). Maybe related to bug 1490172.

Version-Release number of selected component (if applicable):
- Linux HOSTNAME 4.15.10-300.fc27.x86_64 #1 SMP Thu Mar 15 17:13:04 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
- linux-firmware.noarch 20171215-82.git2451bb22.fc27
- Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter (rev 32)
- Dell XPS 13 9370 laptop

How reproducible:

Steps to Reproduce:
1. Upgrade kernel to 4.15.10
2. Use the ath10k_pci driver with the jQualcomm Atheros network card
3. Wait and see

Actual results:
