block/write-threshold: drop extra APIs
bdrv_write_threshold_exceeded() is unused. bdrv_write_threshold_is_set() is used only to double check the value of bs->write_threshold_offset in tests. No real sense in it (both tests do check real value with help of bdrv_write_threshold_get()) Signed-off-by: Vladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com> Reviewed-by: Max Reitz <mreitz@redhat.com> Message-Id: <20210506090621.11848-5-vsementsov@virtuozzo.com> Reviewed-by: Eric Blake <eblake@redhat.com> Reviewed-by: Stefan Hajnoczi <stefanha@redhat.com> [mreitz: Adjusted commit message as per Eric's suggestion] Signed-off-by: Max Reitz <mreitz@redhat.com>
