Revert "openssh: Don't try to bind to unsupported addresses"

This doesn't actually do anything useful, since getifaddrs() will only
return supported addresses. The root cause of the issue described in
the PR lies earlier in the connection timeline, around the start of the
ssh_create_socket() function.

This reverts commit e5ff8e7977434b150a66bb3e472c6d0e0f644cfa.
