kern: improve simple lock debugging

Do not bother saving the return address when acquire a simple lock.
Save the location as provided by the compiler as string instead.  Also
save the lock parameter.

* kern/lock.c (struct simple_locks_info): Drop `ra', add `expr', `loc'.
(simple_lock): Rename to `_simple_lock', add expression and location
parameters and save them.
(simple_lock_try): Likewise.
(simple_unlock): Zero-out the now unused slot in the list of taken locks.
(db_show_all_slocks): Use the new information.
* kern/lock.h (simple_lock, simple_lock_try): Provide macro versions
passing the location and expression as string.
