[PATCH V2] lockdep: Use different indentation in print_lock_class_header/print_lock_trace

[Joe Perches]

This code that uses the printk return value in
kernel/locking/lockdep.c is odd because the printk
return value includes both the length of a KERN_<LEVEL>
prefix and a newline.  depth is also double counted.

Change the code to use depth + 3 + strlen.

v2: sigh: add missing close parenthesis, dunno what happened
