iscsi/iser-target: Use list_del_init for ->i_conn_node

There are a handful of uses of list_empty() for cmd->i_conn_node
within iser-target code that expect to return false once a cmd
has been removed from the per connect list.

This patch changes all uses of list_del -> list_del_init in order
to ensure that list_empty() returns false as expected.
