lib/relocator: Initialize local relocator subchunk struct to all zeros

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.

Fixes: CID 314016
