HID: i2c-hid-of: fix NULL-deref on failed power up
A while back the I2C HID implementation was split in an ACPI and OF
part, but the new OF driver never initialises the client pointer which
is dereferenced on power-up failures.
Fixes: b33752c30023 ("HID: i2c-hid: Reorganize so ACPI and OF are separate modules")
