Subject: [PATCH net v2 1/3] ice: Fix stats after PF reset

From: Ahmed Zaki <ahmed.zaki@...el.com>

After a core PF reset, the VFs were showing wrong Rx/Tx stats. This is a
regression in commit 6624e780a577 ("ice: split ice_vsi_setup into smaller
functions") caused by missing to set "stat_offsets_loaded = false" in the
ice_vsi_rebuild() path.

Fixes: 6624e780a577 ("ice: split ice_vsi_setup into smaller functions")
