[PATCH v2 03/18] unpack-trees: simplify verify_absent_sparse()

["Elijah Newren via GitGitGadget" <gitgitgadget@gmail.com>]

From: Elijah Newren <newren@gmail.com>

verify_absent_sparse() was introduced in commit 08402b0409
("merge-recursive: distinguish "removed" and "overwritten" messages",
2010-08-11), and has always had exactly one caller which always passes
error_type == ERROR_WOULD_LOSE_UNTRACKED_OVERWRITTEN.  This function
then checks whether error_type is this value, and if so, sets it instead
to ERROR_WOULD_LOSE_ORPHANED_OVERWRITTEN.  It has been nearly a decade
and no other caller has been created, and no other value has ever been
passed, so just pass the expected value to begin with.
