[PATCH 23/27] submodule: die_path_inside_submodule is sparse aware

From
Derrick Stolee via GitGitGadget <gitgitgadget@gmail.com>

Message-ID
<6b9f935b87aec1806f48294574924fc26c4abbc7.1611596534.git.gitgitgadget@gmail.com>
In-Reply-To
<pull.847.git.1611596533.gitgitgadget@gmail.com>
From: Derrick Stolee <dstolee@microsoft.com>

Since we already do not collapse a sparse directory if it contains a submodule, we don't need to expand to a full index in die_path_inside_submodule(). A simple scan of the index entries is sufficient.
