[PATCH iwl-net 1/2] ice: move ice_vsi_realloc_stat_arrays() up

[Przemek Kitszel <przemyslaw.kitszel@intel.com>]

Move ice_vsi_realloc_stat_arrays() up, to allow calling it from
ice_vsi_cfg_def() by the next commit.

Fix kdoc for touched code. One line break removed, "int i" scope
minimized to the loop, no changes otherwise.
