Subject: [PATCH] lockdep: Use info level for lockdep initial info messages

All those:
 Lock dependency validator: Copyright (c) 2006 Red Hat, Inc., Ingo Molnar
 ... MAX_LOCKDEP_SUBCLASSES:  8
 ... MAX_LOCK_DEPTH:          48
 ... MAX_LOCKDEP_KEYS:        8192
and so on are dumped with the KERN_WARNING level. It is due to missing
KERN_* annotation.

Use pr_info() instead of bare print() to dump the info with the info
level.
