upload-pack: fix off-by-one depth calculation in shallow clone

get_shallow_commits() is used to determine the cut points at a given
depth (i.e. the number of commits in a chain that the user likes to
get). However we count current depth up to the commit "commit" but we
do the cutting at its parents (i.e. current depth + 1). This makes
upload-pack always return one commit more than requested. This patch
fixes it.
