iproute2: tc/m_pedit.c - remove dead code

The initializers are simply not needed.

These if-blocks are outright dead code, because '0 > unsigned' is always
false, so only else clause triggers and regardless of which clause triggers
it only updates 'ind' which is later unconditionally written to before
being used anyway.

Otherwise we get errors from clang:

  m_pedit.c:166:8: error: comparison of 0 > unsigned expression is always false [-Werror,-Wtautological-compare]
    if (0 > tkey->off) {
        ~ ^ ~~~~~~~~~
  m_pedit.c:209:8: error: comparison of 0 > unsigned expression is always false [-Werror,-Wtautological-compare]
    if (0 > tkey->off) {
        ~ ^ ~~~~~~~~~
  2 errors generated.
