scsi: fcoe: Remove fcoe_select_cpu()

The function fcoe_select_cpu() is just used to distribute incoming skbs
which start a new FC command sequence. But the network stack already
received (and processed) that skb, and there is a _really_ good chance
that all subsequent skbs for this sequence will be handled with the same
CPU. So we should just use the CPU on which this skb was allocated on and
save ourselves some overhead due to pointless scheduling.
