upload-pack: change multi_ack to an enum 

As we cleanup 'upload-pack.c' by using 'struct upload_pack_data'
more thoroughly, let's take this opportunity to change the
'multi_ack' variable, which is now part of 'upload_pack_data',
to an enum.

This will make it clear which values this variable can take.
