Lin Ma b65b13d01b scsi: be2iscsi: Add length check when parsing nlattrs
[ Upstream commit ee0268f230f66cb472df3424f380ea668da2749a ]

beiscsi_iface_set_param() parses nlattr with nla_for_each_attr and assumes
every attributes can be viewed as struct iscsi_iface_param_info.

This is not true because there is no any nla_policy to validate the
attributes passed from the upper function iscsi_set_iface_params().

Add the nla_len check before accessing the nlattr data and return EINVAL if
the length check fails.
