[git commit] ash: remove no-longer-used variable

[Denys Vlasenko]

commit: https://git.busybox.net/busybox/commit/?id=7344755823df5510b089cc5db30f8c1cdebdc5a2
branch: https://git.busybox.net/busybox/commit/?id=refs/heads/master

As of 035486c75 (ash: significant overhaul of redirect saving logic,
2017-07-31), the sv_pos variable is no longer used (just assigned to,
with no further effect).

Let's just remove it.
