[PATCH] osmo-bts[master]: osmo-bts-trx: Fix missing frame number in MEAS IND

osmo-bts-trx: Fix missing frame number in MEAS IND

The layer 1 interface (l1_if.c) for osmo-trx does not include
the frame number into the measurement indications it forwards
to higher layers. The frame number is required to properly
detect the end of a measurement period.

This commit changes l1if_fill_meas_res() to properly include
the frame number into the l1sap primitive (struct osmo_phsap_prim *l1sap)
