Fix possible UB by checking for null allocating FX.
...
Namely, the global allocator API in Rust, actually only returns a null
pointer on failure, rather than wrapping it in a Result, which AllocRef
does. Since Box::from_raw(null) is direct UB, this can in theory lead to
very strange behavior.

WIP: Stop using recursive mapping.
...
Note that this is very preliminary, and I merely got my already freezing
kernel branch not to triple fault, but I would probably apply this patch
to upstream.
What is changed here, is that rather than relying on recursive mapping
for accessing page table frames, it now uses linear translation
(virt=phys+KERNEL_OFFSET). The only problem is that the paging code now
makes assumptions that the entire physical address space remains mapped,
which is not necessarily the case on x86_64 architecturally, even though
systems with RAM more than a PML4 are very rare. We'd probably lazily
(but linearly) map physical address space using huge pages.
