Bluetooth: hci_qca: Avoid setup failure on missing rampatch
[ Upstream commit ba8f3597900291a93604643017fff66a14546015 ] Assuming that the original code idea was to enable in-band sleeping only if the setup_rome method returns succes and run in 'standard' mode otherwise, we should not return setup_rome return value which makes qca_setup fail if no rampatch/nvm file found. This fixes BT issue on the dragonboard-820C p4 which includes the following QCA controller: hci0: Product:0x00000008 hci0: Patch :0x00000111 hci0: ROM :0x00000302 hci0: SOC :0x00000044 Since there is no rampatch for this controller revision, just make it work as is.
