ipa: Be consistent in checking conn->cfg (Coverity)
Coverity complains about checking connection->cfg in
bsc_close_connection() at one place but not at the second.
This patch fixes this by adding a check before accessing cfg when
generating the 'partial message' log message.
Fixes: Coverity CID 1195180
