IB/mlx4: Fix uninitialized-var warning in mlx4_ib_post_send()

    drivers/infiniband/hw/mlx4/qp.c: In function 'mlx4_ib_post_send':
    drivers/infiniband/hw/mlx4/qp.c:1460: warning: 'seglen' may be used uninitialized in this function

This is the dopey gcc-doesn't-know-that-foo(&var)-writes-to-var problem.
