iscsi-target: avoid NULL pointer in iscsi_copy_param_list failure
In iscsi_copy_param_list() a failed iscsi_param_list memory allocation currently invokes iscsi_release_param_list() to cleanup, and will promptly trigger a NULL pointer dereference. Instead, go ahead and return for the first iscsi_copy_param_list() failure case. Found by coverity.
