Subject: [net PATCH] octeontx2-pf: Dont allocate BPIDs for LBK interfaces

Current driver enables backpressure for LBK interfaces.
But these interfaces do not support this feature.
Hence, this patch fixes the issue by skipping the
backpressure configuration for these interfaces.

Fixes: 75f36270990c ("octeontx2-pf: Support to enable/disable pause frames via ethtool").
