Paolo Bonzini a53f1a95f9 block: get_block_status: use "else" when testing the opposite condition 
A bit of Boolean algebra (and common sense) tells us that the
second "if" here is looking for blocks that are not allocated.
This is the opposite of the "if" that sets BDRV_BLOCK_ALLOCATED,
and thus it can use an "else".
