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.
