mm: proc: smaps_rollup: fix pss_locked calculation
commit 27dd768ed8db48beefc4d9e006c58e7a00342bde upstream.
The 'pss_locked' field of smaps_rollup was being calculated incorrectly.
It accumulated the current pss everytime a locked VMA was found. Fix
that by adding to 'pss_locked' the same time as that of 'pss' if the vma
being walked is locked.
