mm/page_alloc.c:__alloc_pages_nodemask(): don't alter arg gfp_mask

__alloc_pages_nodemask() strips __GFP_IO when retrying the page
allocation.  But it does this by altering the function-wide variable
gfp_mask.  This will cause subsequent allocation attempts to inadvertently
use the modified gfp_mask.

Also, pass the correct mask (the mask we actually used) into
trace_mm_page_alloc().
