Bluetooth: hci_qca: Avoid missing rampatch failure with userspace fw loader
commit 7dc5fe0814c35ec4e7d2e8fa30abab72e0e6a172 upstream.
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.
