lockdep: fix unused function warning in kernel/lockdep.c

Impact: fix build warning

this warning:

  kernel/lockdep.c:584: warning: ‘print_lock_dependencies’ defined but not used

triggers because print_lock_dependencies() is only used if both
CONFIG_TRACE_IRQFLAGS and CONFIG_PROVE_LOCKING are enabled.

But adding #ifdefs is not an option here - it would spread out to 4-5
other helper functions and uglify the file. So mark this function
as __used - it's static and the compiler can eliminate it just fine.
