util/vl: initialize data/end pointers.

Browse source 
Since this util moved to public place it turned out it could cause
a build error on current CI like the following:

../src/util/vl_vlc.h:225:52: error: 'vlc.data' may be used uninitialized in this function [-Werror=maybe-uninitialized]
  225 |    assert(vl_vlc_valid_bits(vlc) >= num_bits || vlc->data >= vlc->end);
      |                                                    ^~
../src/util/vl_vlc.h:225:65: error: 'vlc.end' may be used uninitialized in this function [-Werror=maybe-uninitialized]
  225 |    assert(vl_vlc_valid_bits(vlc) >= num_bits || vlc->data >= vlc->end);
