bnx2x: no error when RSS configuration fails
It's possible for VMs with older versions of bnx2x to run over a hypervisor with latest driver. If a VF in such a VM does not support RSS configuration, the PF driver in the hypervisor will print an error message to system logs. This changes the error message into a debug message, as this is very likely a false alarm for an older VF (i.e., VF manages to work properly; PF simply cannot configure the additional queues for it).
