mm: process reclaim: skip locked vmas
Skip VMA_LOCKED vmas from being reclaimed. Not doing so results
in pages in unevictable lrus to be passed for reclaim which can
cause issues. In one such reported problem, the trylock_page in
shrink_page_list fails and reclaim path decides to keep the page
and hits VM_BUG_ON_PAGE since PageUnevictable is set.
