[PATCH 07/13] upload-pack: use upload_pack_data writer in receive_needs()

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

As we cleanup 'upload-pack.c' by using 'struct upload_pack_data'
more thoroughly, let's use the 'struct packet_writer writer'
field from 'struct upload_pack_data' in receive_needs(),
instead of a local 'struct packet_writer writer' variable.
