sysctl: remove redundant assignment to first
Variable first is set to '0', but this value is never read as it is not
used later on, hence it is a redundant assignment and can be removed.
Clean up the following clang-analyzer warning:
kernel/sysctl.c:1562:4: warning: Value stored to 'first' is never read
[clang-analyzer-deadcode.DeadStores].
