iscsi: Change the ordering to alloc string of options at initialization

Browse Source 
In JSON-RPC, string is allocated unconditionally in decode operation.
Hence if string is allocated in opts_init(), it will be overwritten without
any notice.

This patch is to keep compatibility to the config file and adjust to the
upcoming JSON-RPC for options initialization.
