ANDROID: mm: fix up removal of vm_total_pages problem

Browse Source 
commit 92501cb670 ("ANDROID: add extra free kbytes tunable") added a
use of the vm_total_pages variable, which is now gone upstream.

So fix this up with a call to
nr_free_zone_pages(gfp_zone(GFP_HIGHUSER_MOVABLE) instead, which I
_think_ is the equivalent value.  Hopefully :)
