[kvm-unit-tests PATCH v1 2/4] lib/alloc_page: change some parameter types

[Claudio Imbrenda <imbrenda@linux.ibm.com>]

For size parameters, size_t is probably semantically more appropriate
than unsigned long (although they map to the same value).

For order, unsigned long is just too big. Also, get_order returns an
unsigned int anyway.
