vm: optimise page array size and initialisation.
...
* the page array now only extends up to the last non-reserved memory frame.
* rather than memset'ing the whole array to zero, we only initialise p_flags
for each page in vm_page_array_init, and then leave it to group_pages_into_block
to initialise the other parts of vm_page_t.
