smbd: Simplify chroot option in smbd
rpmlint has a check for this and prefers to call chdir() before
chroot(). If not it will complain with
missing-call-to-chdir-with-chroot. The old code equivalent secure. See
http://unixwiz.net/techtips/chroot-practices.html
This removes several unneeded talloc_tos() calls.
