[net PATCH 2/2] octeontx2-af: fix lbk link credits on cn10k

[Naveen Mamindlapalli]

From: Nithin Dabilpuram <ndabilpuram@xxxxxxxxxxx>

Fix LBK link credits on CN10K to be same as CN9K i.e
16 * MAX_LBK_DATA_RATE instead of current scheme of
calculation based on LBK buf length / FIFO size.

Fixes: 6e54e1c5399a ("octeontx2-af: cn10K: Add MTU configuration")
