[S390] Fix gcc 4.6.0 compile warning

Browse source 
With gcc 4.6.0 we get a false compile warning:

 arch/s390/kernel/setup.c: In function 'setup_arch':
 arch/s390/kernel/setup.c:767:3: warning: 'msg' may be used
            uninitialized in this function [-Wuninitialized]
 arch/s390/kernel/setup.c:753:8: note: 'msg' was declared here

This patch makes gcc quiet.
