[PATCH v2 1/9] midx.c: clean up chunkfile after reading the MIDX

[Taylor Blau <me@ttaylorr.com>]

In order to read the contents of a MIDX, we initialize a chunkfile
structure which can read the table of contents and assign pointers into
different sections of the file for us.

We do call free(), since the chunkfile struct is heap allocated, but not
the more appropriate free_chunkfile(), which also frees memory that the
structure itself owns.

Call that instead to avoid leaking memory in this function.
