i40e: Lock for VSI's MAC filter list
This patch introduces a spinlock which is to be used for synchronizing access to VSI's MAC filter list. This patch also synchronizes execution of other codepaths which are accessing VSI's MAC filter list with execution of service_task:sync_vsi_filters. In function i40e_add_vsi, copied out LAA MAC address instead of cloning MAC filter entry because only MAC address is needed to remove MAC VLAN filter from FW/HW.
