s390/lcs: Fix null-pointer access in msg
An attempt to configure a CTC device as LCS results in the following error message: (null): Detecting a network adapter for LCS devices failed with rc=-5 (0xfffffffb) "(null)" results from access to &card->dev->dev in lcs_new_device() which is only initialized later in the function. Fix this by using &ccwgdev->dev instead which is initialized before lcs_new_device() is called.
