mm: page_alloc: use unsigned int for order in more places
commit 7aeb09f9104b760fc53c98cb7d20d06640baf9e6 upstream.
X86 prefers the use of unsigned types for iterators and there is a
tendency to mix whether a signed or unsigned type if used for page order.
This converts a number of sites in mm/page_alloc.c to use unsigned int for
order where possible.
