[PATCH] multi-pack-index: make code -Wunused-parameter clean

["Carlo Marcelo Arenas Belón" <carenas@gmail.com>]

introduced in 662148c435 ("midx: write object offsets", 2018-07-12)
but included on all previous versions as well.

midx.c:713:54: warning: unused parameter 'nr_objects' [-Wunused-parameter]

likely an oversight as the information needed to iterate over is
embedded in nr_large_offset
