s390/debug: Remove s390dbf_sysctl_header variable
allmodconfig with clang W=1 points out an unused global variable:
arch/s390/kernel/debug.c:1237:33: error: variable
's390dbf_sysctl_header' set but not used [-Werror,-Wunused-but-set-global]
Just remove the variable. There is no point in adding error handling for a
failing register_sysctl() call.
