When enabling or disabling the vcpu dispatch statistics, we do a lot of
work including allocating/deallocating memory across all possible cpus
for the DTL buffer. In order to guard against hogging the cpu for too
long, track the time we're taking and yield the processor if necessary.

walk_memory_range() was once used to iterate over sections. Now, it
iterates over memory blocks. Rename the function, fixup the
documentation. Also, pass start+size instead of PFNs, which is what most
callers already have at hand. (we'll rework link_mem_sections() most
probably soon)
Follow-up
Block ids are just shifted section numbers, so let's also use
"unsigned long" for them, too.
