[PATCH 05/13] upload-pack: pass upload_pack_data to get_common_commits()

[Christian Couder <christian.couder@gmail.com>]

As we cleanup 'upload-pack.c' by using 'struct upload_pack_data'
more thoroughly, let's pass 'struct upload_pack_data' to
get_common_commits(), so that this function and the functions
it calls can use all the fields of that struct in followup
commits.
