LCS network driver fixes:
 - Fix ccwgroup behaviour, remove should offline cards still online.
 - Better not write to the debug feature before it is registers.
 - Don't free card structure on offline but on remove.
 - Check for deferred condition code 1 in lcs_irq for halt requests.
 - Call free_netdev only if there is a net device.
