L2FIB:fix crash in show with deleted subif entries
after deleting a sub interface it's l2fib entries are left with a dangling sw_if_index (while waiting for the ager to delete them). changed "show l2fib" to reflect that state with "Deleted" as the interface name. added sleep in test_l2_fib as a workaround for packets still passing after flush will investigate...
