feijermu 9cbfcf39da Add a null check to NetUtil. sysctlGetInt(...) (#10027)
Motivation:

BufferedReader.readLine() may return null and cause a NPE.

Modification:

Simply add a null check.

Result:

If BufferedReader.readLine() returns null, the sysctlGetInt will just return null rather than cause NPE.
