I have the same problem o Debian with firmware ver RM.4.4.1.c2-00057-QCARMSWP-1 api 6, but I finally managed to reset the device without reboot:

    # remove faulty module:
    sudo modprobe -r ath10k_pci
    # lspci shows card being in the slot 03:00.0
    # tried resetting first, didn't help. Probably irrelevant:
    echo 1 | sudo tee /sys/bus/pci/devices/0000\:03\:00.0/reset
    # remove device:
    echo 1 | sudo tee /sys/bus/pci/devices/0000\:03\:00.0/remove
    # rescan PCI:
    echo 1 | sudo tee /sys/bus/pci/rescan
    # probably irrelevant:
    echo 1 | sudo tee /sys/bus/pci/drivers_autoprobe
    # load module back:
    sudo modprobe ath10k_pci
