Subject: nfp: fix TLV offset calculation
Patch-mainline: v4.16-rc1
Git-commit: 1d8ef0c07664dc48f2ff19a90b62dd3f6f425547
References: bsc#1109837
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")
