platform/chrome: kunit: initialize lock for fake ec_dev

Browse Source 
cros_ec_cmd_xfer() uses ec_dev->lock.  Initialize it.

Otherwise, dmesg shows the following:
> DEBUG_LOCKS_WARN_ON(lock->magic != lock)
> ...
> Call Trace:
>  ? __mutex_lock
>  ? __warn
>  ? __mutex_lock
>  ...
>  ? cros_ec_cmd_xfer
