ath11k: mhi: print a warning if firmware crashed
There was no way to detect if the firmware crashed so add a warning. At the
moment the firmware is not restarted or anything like that, so when this
happens ath11k modules need to be reloaded.
Tested-on: QCA6390 hw2.0 PCI WLAN.HST.1.0.1-01740-QCAHSTSWPLZ_V2_TO_X86-1
