[PATCH] Initialize local relocator subchunk struct to all zeros

[Ross Philipson]

The way the code is written the tofree variable would never be
passed to the free_subchunk() function uninitialized. Coverity
cannot determine this and flags the situation as "Using uninitialized
value...". The fix is just to initialize the local struct.
