Subject: IB/{core, ipoib}: Simplify ib_find_gid to search only for IB link
layer
Patch-mainline: v4.16-rc1
Git-commit: dbb12562f7c2377c210ed6b2e79eda5bfe23c30c
References: bsc#1103992 FATE#326009
Currently there are no users of ib_find_gid for RoCE transport. It is
only used by IPoIB.
Therefore its simplified to ignore RoCE ports and GID type check which
was previously done for every port.
