Subject: [PATCH blk-next 2/2] RDMA/core: Delete not-implemented get_vector_affinity

From: Leon Romanovsky <leonro@...dia.com>

There are no drivers that support .get_vector_affinity(), so delete it.

Fixes: 9afc97c29b03 ("mlx5: remove support for ib_get_vector_affinity")
Signed-off-by: Leon Romanovsky <leonro@...dia.com>
