Subject: [PATCH] nfp: fix TLV offset calculation
The data pointer in the config space TLV parser already includes
NFP_NET_CFG_TLV_BASE, it should not be added again. Incorrect
offset values were only used in printed user output, rendering
the bug merely cosmetic.
Fixes: 73a0329b057e ("nfp: add TLV capabilities to the BAR")
