KVM: selftests: Keep dirty_log_test vCPU in guest until it needs to stop
In the dirty_log_test guest code, exit to userspace only when the vCPU is
explicitly told to stop. Periodically exiting just to check if a flag has
been set is unnecessary, weirdly complex, and wastes time handling exits
that could be used to dirty memory.
Opportunistically convert 'i' to a uint64_t to guard against the unlikely
scenario that guest_num_pages exceeds the storage of an int.
