Subject: [PATCH] net/mlx4_core: Add immediate activate for VGT->VST->VGT

Allow immediate activate of VGT->VST and VST->VGT transitions, without
the need of rebinding in mlx4_master_immediate_activate_vlan_qos().

Also in struct res_qp: add qp parameters (vlan_index,fvl,vlan_cntrol..)
to the saved set, in order to restore when move to VGT.
 - Clear at mlx4_RST2INIT_QP_wrapper()
 - Save at mlx4_INIT2RTR_QP_wrapper()
 - Restore at mlx4_vf_immed_vlan_work_handler()

Update mlx4_vf_immed_vlan_work_handler() to support VGT.
