Revert "update neighbor ARFCNs on startup and config changes"

This patch caused major breakage in my setup, with BSC printing at
startup: "(bts=0,trx=0) Failed to generate System Information".

And bts-trx printing all the time:
"sysinfo.c:162 PH-RTS-IND: Unable to determine actual BS_AG_BLKS_RES
value as SI3 is not available yet, fallback to 1"

This reverts commit c1a5310a3e.
