Merge branch 'md/list-objects-filter-memfix' into maint

The filter_data used in the list-objects-filter (which manages a
lazily sparse clone repository) did not use the dynamic array API
correctly---'nr' is supposed to point at one past the last element
of the array in use.  This has been corrected.

* md/list-objects-filter-memfix:
  list-objects-filter: correct usage of ALLOC_GROW
