block/get_block_status: fix BDRV_BLOCK_ZERO for unallocated blocks
this patch does 2 things:
a) only do additional call outs if BDRV_BLOCK_ZERO is not already set.
b) use the newly introduced bdrv_unallocated_blocks_are_zero()
to return the zero state of an unallocated block. the used callout
to bdrv_has_zero_init() is only valid right after bdrv_create.
