Revert "net/smc: Replace ib_query_gid with rdma_get_gid_attr"
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.
