mm, lockdep: annotate reclaim context to zone reclaim too

Browse source

Commit cf40bd16fd ("lockdep: annotate reclaim context") introduced reclaim
context annotation.  But it didn't annotate zone reclaim.  This patch do
it.

The point is, commit cf40bd16fd annotate __alloc_pages_direct_reclaim but
zone-reclaim doesn't use __alloc_pages_direct_reclaim.

current call graph is

__alloc_pages_nodemask
   get_page_from_freelist
       zone_reclaim()
   __alloc_pages_slowpath
       __alloc_pages_direct_reclaim
           try_to_free_pages

Actually, if zone_reclaim_mode=1, VM never call
__alloc_pages_direct_reclaim in usual VM pressure.
