Log message:
Reimplement Grant Table metadata linking and enable dynamic allocation
Instead of pre-allocating maximum number of Grant Table frames allotted by
the hypervisor we switch over to allocating them dynamically when the need
arises. At the same time we no longer link metadata entries representing
individual Grant Table frames as a list and use a table instead to speed
up reference lookups when establishing and removing mappings.
