i40e: remove redundant check on vsi->active_vlans

active_vlans is an unsigned long array, hence a null check on this
array is superfluous and can be removed.

Detected with static analysis by smatch:

drivers/net/ethernet/intel/i40e/i40e_debugfs.c:386
  i40e_dbg_dump_vsi_seid() warn: this array is probably
  non-NULL. 'vsi->active_vlans'
