[PATCH 06/11] sha1-file: convert pass-through functions to object_id




These two static functions, read_object() and quick_has_loose(), both
have to hashcpy() their bare-sha1 arguments into object_id structs to
pass them along. Since all of their callers actually have object_id
structs in the first place, we can eliminate the copying by adjusting
their input parameters.
