Alexander Duyck 7c8ae65a62 ixgbe: Make FCoE allocation and configuration closer to how rings work 
This patch changes the behavior of the FCoE configuration so that it is
much closer to how the main body of the ixgbe driver works for ring
allocation.

The first piece is the ixgbe_fcoe_ddp_enable/disable calls.  These allocate
the percpu values and if successful set the fcoe_ddp_xid value indicating
that we can support DDP.

The next piece is the ixgbe_setup/free_ddp_resources calls.  These are
called on open/close and will allocate and free the DMA pools.

Finally ixgbe_configure_fcoe is now just register configuration.  It can go
through and enable the registers for the FCoE redirection offload, and FIP
configuration without any interference from the DDP pool allocation.

The net result of all this is two fold.  First it adds a certain amount of
exception handling.  So for example if ixgbe_setup_fcoe_resources fails we
will actually generate an error in open and refuse to bring up the
interface.

Secondly it provides a much more graceful failure case than the previous
model which would skip setting up the registers for FCoE on failure to
allocate DDP resources leaving no Rx functionality enabled instead of just
disabling DDP.
