Remove freelist reference in buf_init.c
Hi All,
We have gotten rid of freelist in buffer manager, but buf_init.c still
has a reference to it in a comment. Patch to remove the reference.
Other references to freelist refer to freelist.c which is still a
valid filename reference. Hence I didn't touch it.

I'm not sure this enough of an improvement to really be worth it. I think we
probably ought to rename freelist.c to buf_replacement.c or such. Which of
course will require more comment changes.
Even if we don't, I think that the entire comment in buf_init.c is misplaced
and bound to not be updated. Nobody is looking for it there, both when trying
to learn about the code and when changing the code.

Hmm,
I think that whole comment block is misleading; it seems to be
outdated or at least incomplete. We have two options
1. Replace the comment block with a comment block mentioning all the
shared memory structures that buffer manager uses, their purpose, and
point to respective comments in buf_internals.h.
2. Remove that comment entirely from there and add the comment block
as above to README.
