Kevin Wolf 8f1efd00c4 qcow2: Fix bdrv_write_compressed error handling 
If during allocation of compressed clusters the cluster was already allocated
uncompressed, fail and properly release the l2_table (the latter avoids a
failed assertion).

While at it, make it return some real error numbers instead of -1.
