trx: detect UL SID in EFR just like in FR
The TCH/F Rx code in osmo-bts-trx uses osmo_fr_check_sid() to detect when the MS sends SID, and passes the flag to lchan_set_marker(). However, equivalent logic was missing for EFR, as until recently there was no EFR SID check function in libosmocodec. Now that we have osmo_efr_check_sid(), use it.
