[PATCH 1/2] parse_object(): drop extra "has" check before checking object type

When parsing an object of unknown type, we check to see if it's a blob, so we can use our streaming code path. This uses oid_object_info() to check the type, but before doing so we call repo_has_object_file(). This latter is pointless, as oid_object_info() will already fail if the object is missing. Checking it ahead of time just complicates the code and is a waste of resources (albeit small).

Let's drop the redundant check.
