Bluetooth: hci_qca: Avoid missing rampatch failure with userspace fw loader
AOSP use userspace firmware loader to load firmwares, which will return -EAGAIN in case qca/rampatch_00440302.bin is not found. Since there is no rampatch for dragonboard820c QCA controller revision, just make it work as is.
