CHROMIUM: mm: Fix calculation of dirtyable memory

The system uses global_dirtyable_memory() to calculate
number of dirtyable pages/pages that can be allocated
to the page cache.  A bug causes an underflow thus making
the page count look like a big unsigned number.  This in turn
confuses the dirty writeback throttling to aggressively write
back pages as they become dirty (usually 1 page at a time).

Fix is to ensure there is no underflow while doing the math.

 *   0 - disabled (default)
 *   1 - substitute AC to USB
 *   2 - use custom mA configured through sysfs interface (see below)

 *
 *   0 - disabled - allow anything up to 2.1A/h to be used as AC / USB custom current
 *   1 - enabled  - behaviour as described above (default)
