Subject: [PATCH] (closes issue #13089) Reported by: murf

Most of this bug was already fixed by Tilghman before
I opened it; Many thanks to Tilghman for his fix
in svn version 125794. That fix cleared up some of the
fields in the lock_info.

This commit changes the address that is stored for the
lock in the lock_info struct, so that it is the same
as that passed into the locking macros. This makes
searching for a lock_info (as in log_show_lock())
by its lock addr possible. The lock_addr field is
infinitely more useful if it is the same as what
is 'publicly' available outside the lock_info code.

Many thanks to kpfleming, putnopvut, and Russell for their
invaluable insights earlier today.
