iwpmd: Zero-initialize the remote addr info

[ Upstream commit 3fcf920 ]

The remote addr info can be padded with random bytes
if not initialized. The remote addr info is stored in the
iw_cm module, looked up and passed to applications later.

Fixes: eee8aef ("rdma-core/iwpmd: Add functionality to enable libiwpm to provide the remote connecting peer address information to its clients")
