upload-pack: pass upload_pack_data to receive_needs()

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