Subject: [PATCH v1 3/7] HID: playstation: DS4: Don't fail on FW/HW version request

Some third-party controllers can't report firmware/hardware version.

Unlike for the DualSense, the driver does not use these values for
anything in the DualShock 4 case, but merely exposes them via sysfs.
They will simply be 0x0.
