Subject: [PATCH net-next 12/17] tipc: Minor optimization to topology service connection establishment

From: Allan Stephens <Allan.Stephens@...driver.com>

Eliminates a local iovec structure containing no data, which was
previously used during the establishment of a topology service connection,
since the same effect can be achieved by passing in a NULL pointer and
an iovec length of zero.
