[PATCH 02/14] upload-pack: pass upload_pack_data to deepen()

[Christian Couder <christian.couder@xxxxxxxxx>]

As we cleanup 'upload-pack.c' by using 'struct upload_pack_data'
more thoroughly, let's pass that struct to deepen(), 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'.
