Fix PSS correlation peak value and average value on the OAI UE logs (#274)

These metrics are very helpful to properly adjust the USRP gains on the OAI UE. There was a regression in the code, this commit just gets it showing properly again.

Current develop:

    [NR_PHY] Starting sync detection
    [PHY]    [UE thread Synch] Running Initial Synch
    [NR_PHY] Starting cell search with center freq: 3619200000, bandwidth: 106. Scanning for 1 number of GSCN.
    [NR_PHY] Scanning GSCN: 0, with SSB offset: 516, SSB Freq: 0.000000
    [PHY]    Initial sync: pbch decoded sucessfully, ssb index 0
    [PHY]    pbch rx ok. rsrp:51 dB/RE, adjust_rxgain:-1 dB
    [NR_PHY] Cell Detected with GSCN: 0, SSB SC offset: 516, SSB Ref: 0.000000, PSS Corr peak: 0 dB, PSS Corr Average: 0
