upload-pack: pass upload_pack_data to send_unshallow()

As we cleanup 'upload-pack.c' by using 'struct upload_pack_data'
more thoroughly, let's pass that struct to send_unshallow(), so
that this function can use all the fields of the struct.

This will be used in followup commits to move static variables
into 'upload_pack_data'.
