fcoe: prep work to start consolidate the usage of fcoe_netdev
Currently, in the default kernel fcoe driver, it is needed to get to the underlying private per fcoe transport's private structure, e.g., fcoe_interface in fcoe.ko, and returns the associated netdev. The similar logic exists in other fcoe drivers, e.g., bnx2fc, so we add a function pointer into the common fcoe_port struct to allow individual fcoe transport implementaion (fcoe and bnx2fc) to get the corresponding netdev associated with a give lport. Then a inline fcoe_get_netdev() is added as part of libfcoe for all underlying fcoe transport drivers to use regardless of its individual fcoe transport driver, and also allows move more common code such as fcoe_link_speed_update or fcoe_ctlr_get_lesb to be in libfcoe, rather than specific to fcoe. This patch is a prep work that adds aforementioned fucntion pointer, and followed by the actual code changes to make use of it.
