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...
