block/backup: refactor and tolerate unallocated cluster skipping

Split allocation checking to separate function and reduce nesting.
Consider bdrv_is_allocated() fail as allocated area, as copying more
than needed is not wrong (and we do it anyway) and seems better than
fail the whole job. And, most probably we will fail on the next read,
if there are real problem with source.
