receive-pack: release the linked "struct command *" list
Fix a memory leak that's been with us since this code was introduced in [1]. Later in [2] we started using FLEX_ALLOC_MEM() to allocate the "struct command *". 1. 575f497456e (Add first cut at "git-receive-pack", 2005-06-29) 2. eb1af2df0b1 (git-receive-pack: start parsing ref update commands, 2005-06-29) Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
