Subject: [PATCH] iscsiuio: avoid loosing bad rc in nic_nl_open

nic_nl_open might have collected a non-zero rc and jumped to the error
label but still returned zero which would indicate success.

The function should return whatever it has collected in rc and while
working without, also explicitly initialize it to zero.

Fixes #125
