locking/lockdep: Remove the unused print_lock_trace() function

Browse Source 
gcc warns that function print_lock_trace() is unused if
CONFIG_PROVE_LOCKING isn't set:

../kernel/locking/lockdep.c:2820:13: warning: ‘print_lock_trace’ defined but not used [-Wunused-function]

Rework so we remove the function if CONFIG_PROVE_LOCKING isn't set.
