Could you please prefix the summary line as Fix... It makes it easier to
get this to 3.4 as this really must go there. Also explain in the commit
message that the mgmt_device_found expects to receive only the
significant part of the EIR data.

I'm not completely sure about this name. Would eir_significant_len()
sound better? The core spec uses the terminology "significant part" and
non-significant part" to refer to this so I thought reusing that might
make it clearer what we're dealing with.

You should define field_len here instead of the beginning of the
function since it's not used outside of the while-loop.

Add an empty line before the return statement please.
