locking/lockdep: Hide unused 'class' variable
[ Upstream commit 68037aa78208f34bda4e5cd76c357f718b838cbb ]
The usage is now hidden in an #ifdef, so we need to move
the variable itself in there as well to avoid this warning:
kernel/locking/lockdep_proc.c:203:21: error: unused variable 'class' [-Werror,-Wunused-variable]
