RDMA/hns: Fix uninitialized variable bug
There is a potential execution path in which variable *ret* is returned without being properly initialized, previously. Fix this by initializing variable *ret* to 0. Link: https://lore.kernel.org/r/20200328023539.GA32016@embeddedor Addresses-Coverity-ID: 1491917 ("Uninitialized scalar variable") Fixes: 2f49de21f3e9 ("RDMA/hns: Optimize mhop get flow for multi-hop addressing") Signed-off-by: Gustavo A.
