Firmware with the build id QC_IMAGE_VERSION_STRING=WLAN.HL.1.0.2-XXXX does not support the QMI_WLFW_HOST_CAP_REQ_V01 message and will return the QMI not supported error to the ath10k driver. Since not supporting this message is not fatal to the firmware nor the ath10k driver, lets catch this particular scenario and ignore it so that we can still bring up wifi services successfully.
