measurement: Compute measurement results on measurement idication

Computing the measurement results on in l1sap_info_time_ind() all
at once may peak the host CPU. On smaller systems (arm based
sysmobts) this might cause a noticable delay of other important
tasks (e.g. passing l2 messages back and forth) It makes more
sense to compute the measurement results continously when
l1sap_info_meas_ind() is executed.
