sheepdog: Consistently set bdrv_has_zero_init_truncate
block_int.h claims that .bdrv_has_zero_init must return 0 if
.bdrv_has_zero_init_truncate does likewise; but this is violated if
only the former callback is provided if .bdrv_co_truncate also exists.
When adding the latter callback, it was mistakenly added to only one
of the three possible sheepdog instantiations.
