[SCSI] bnx2fc: Allocate fcoe_ctlr with bnx2fc_interface, not as a member
Currently the fcoe_ctlr associated with an interface is allocated
as a member of struct bnx2fc_interface. This causes problems when
when later patches attempt to use the new fcoe_sysfs APIs which
allow us to allocate the bnx2fc_interface as private data to a
fcoe_ctlr_device instance. The problem is that libfcoe wants to
be able use pointer math to find a fcoe_ctlr's fcoe_ctlr_device
as well as finding a fcoe_ctlr_device's assocated fcoe_ctlr. To
do this we need to allocate the fcoe_ctlr_device, with private
data for the LLD. The private data will contain the fcoe_ctlr
and its private data will be the bnx2fc_interface.
+-------------------+
| fcoe_ctlr_device |
+-------------------+
| fcoe_ctlr |
+-------------------+
| bnx2fc_interface |
+-------------------+
This prep work will allow us to go from a fcoe_ctlr_device
instance to its fcoe_ctlr as well as from a fcoe_ctlr to its
fcoe_ctlr_device once the fcoe_sysfs API is in use (later
patches in this series).
