platform/chrome: kunit: initialize lock for fake ec_dev
[ Upstream commit e410b4ade83d06a046f6e32b5085997502ba0559 ]
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
