[PATCH v3 02/18] unpack-trees: remove unused error type

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

From: Elijah Newren <newren@gmail.com>

commit 08402b0409 ("merge-recursive: distinguish "removed" and
"overwritten" messages", 2010-08-11) split
    ERROR_WOULD_LOSE_UNTRACKED
into both
    ERROR_WOULD_LOSE_UNTRACKED_OVERWRITTEN
    ERROR_WOULD_LOSE_UNTRACKED_REMOVED
and also split
    ERROR_WOULD_LOSE_ORPHANED
into both
    ERROR_WOULD_LOSE_ORPHANED_OVERWRITTEN
    ERROR_WOULD_LOSE_ORPHANED_REMOVED

However, despite the split only three of these four types were used.
ERROR_WOULD_LOSE_ORPHANED_REMOVED was not put into use when it was
introduced and nothing else has used it in the intervening decade
either.  Remove it.
