mm: fix leak in fail path

If the dm_realloc would fail, the already allocate _maps_buffer
memory would have been lost (overwritten with NULL).
Fix this by using temporary line buffer.

Also add a minor cleanup to set end of buffer to '\0',
only when we really know the file size fits the preallocated buffer.
