Amit Shah acbbc03661 rng random backend: check for -EAGAIN errors on read ...

Not handling EAGAIN triggers the assert

qemu/backends/rng-random.c:44:entropy_available: assertion failed: (len != -1)
Aborted (core dumped)

This happens when starting a guest with '-device virtio-rng-pci',
issuing a 'cat /dev/hwrng' in the guest, while also doing 'cat
/dev/random' on the host.
