Subject: [net-next 05/15] ice: Introduce a local variable for a VSI in the rebuild path

From: Krzysztof Kazimierczak <krzysztof.kazimierczak@...el.com>

When a VSI is accessed inside the ice_for_each_vsi macro in the rebuild
path (ice_vsi_rebuild_all() and ice_vsi_replay_all()), it is referred to
as pf->vsi[i]. Introduce local variables to improve readability.
