[PATCH] qf: Actually allow qf rebase from a clean environment.

[Rodrigo Vivi]

The intention of commit '663e7293e042 ("qf: Allow rebase
function to start from anywhere.")' was to allow the
qf rebase to start from anywhere, including from a place
where not patch is yet applied with quilt.

However pop -f was not the right answer for that.

We need to make sure that qf pull provides a really clean
environment so qf rebase can really work from scratch to
all (-a) patches.

The goal is that a simple
qf pull && qf rebase drm-tip/drm-tip

Always simply work to rebase from anywhere.

Fixes: 663e7293e042 ("qf: Allow rebase function to start from anywhere.")
