ice: Fix stats after PF reset
[ Upstream commit ab7470bc6d8fb5f3004ccc8e4dfd49aab0f27561 ]
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")
