Subject: Revert "net/smc: Replace ib_query_gid with rdma_get_gid_attr"
Git-commit: 92f4e77c85918eab5e5803d7e28ab89a7e6bd3a2
Patch-mainline: v4.19-rc1
References: FATE#325698, LTC#167867, bsc#1113481

This reverts commit ddb457c6993babbcdd41fca638b870d2a2fc3941.

The include rdma/ib_cache.h is kept, and we have to add a memset
to the compat wrapper to avoid compiler warnings in gcc-7

This revert is done to avoid extensive merge conflicts with SMC
changes in netdev during the 4.19 merge window.
