Stefan Hajnoczi 39ba3bf69c qcow2: fix new_blocks double-free in alloc_refcount_block() 
Commit de82815db1 ("qcow2: Handle failure
for potentially large allocations") introduced a double-free of
new_blocks in the alloc_refcount_block() error path.

The qemu-iotests qcow2 026 test case was failing because qemu-io
segfaulted.

Make sure new_blocks is NULL after we free it the first time.
