KVM: selftests: Use goto instead of do-while to retry finding unused physical pages

Rework the core loop of the physical page allocator to use a goto instead
of do-while loop when retrying with a new base address.  The do-while loop
obviously works, but it obfuscates the success vs. failure paths, and in
general is convoluted.

For all intents and purposes, no functional change intended.
