[B.A.T.M.A.N.] [PATCH 1/7] alfred: Avoid hash search for transaction cleanup

[Sven Eckelmann <sven@narfation.org>]

A transaction can either be cleaned up on timeout or on TXEND. alfred has
in both situations already the head of the transaction list. An extra
search in the transaction hash is therefore not needed.
