Fix a few more warnings
...
Some are important, e.g. the seemingly harmless braces around if with dprintf,
since that dprintf is defined as empty, will screw things up and grab the next
line

x86 mem init: do not map identity mapping
...
init_normal_area was mapping identity lookups (phys = virt) from 0,
leading to many undetected null pointer dereferences in init_pt (but
not in new process page tables leading to odd behaviour)
This also makes the code use the set_pt_large_page() function, cleaning
it up a bit
