Move interface specific cleanup functionality to from bnx2fc_if_destroy to bnx2fc_interface_cleanup. Do not access interface/hba in bnx2fc_if_destroy as by the time this function is called interface may already be destroyed. This patch is in preparation to handle NETDEV_UNREGISTER on a vlan device.
