Tilman Schmidt 5d49c101a1 gigaset: fix Oops on module unload regression 
The card state mutex was only initialized when a device was connected,
but used during unload unconditionally, leading to an Oops if a driver
was loaded and unloaded again without ever connecting a device.

Fix this by initializing the mutex as soon as the structure is allocated.
Also add a missing mutex unlock revealed in the same execution path.

This fixes a possible Oops in 2.6.25-rc that was introduced by commit
e468c04894 ("Gigaset: permit module
unload").

Thanks to Roland Kletzing for reporting this problem.
