Bluetooth: Fix EIR data generation for mgmt_device_found

Browse source 
The mgmt_device_found function expects to receive only the significant
part of the EIR data so it needs to be removed before calling the
function. This patch adds a new eir_get_length() helper function to
calculate the length of the significant part.
