Subject: [PATCH net-next 4/5] ice: Change ice_vsi_realloc_stat_arrays() to void

smatch warnings:
drivers/net/ethernet/intel/ice/ice_lib.c:3612 ice_vsi_rebuild() warn: missing error code 'ret'

If an error is encountered for ice_vsi_realloc_stat_arrays(), ret is not
assigned an error value so the goto error path would return success. The
function, however, only returns 0 so an error will never be reported; due
to this, change the function to return void.
