Subject: [PATCH net-next 04/18] net/mlx4: Aesthetic code changes in multi_func_init

From: Ido Shamay <idos@...lanox.com>

Previous vf_oper and vf_admin code created very long lines, making it hard
to read the code. Added relevant in-struct pointers to reduce code
complexity and avoid code lines spread over 80 lines. Same logic is preserved.
