very small bug fix.

[Kenichi Okuyama]

Dear all,

I beleave there is initialization bug in

./samba-2.0.7pre4/source/parm/loadparm.c

This will not take any effect as long as you're using unix, but it
might on some other OS. So, since I found it, I'll report it :p

here is diff(simple, isn't it :p )

# diff loadparm.c.orig loadparm.c

1118c1118
< static TALLOC_CTX *lp_talloc;
---
> static TALLOC_CTX *lp_talloc = NULL;
