Kevin Wolf 0df93305f2 qcow1: Handle failure for potentially large allocations ...

Some code in the block layer makes potentially huge allocations. Failure
is not completely unexpected there, so avoid aborting qemu and handle
out-of-memory situations gracefully.

This patch addresses the allocations in the qcow1 block driver.
