[CRIU] [PATCHv0 3/8] proc_parse: increase longest in vma list when vma is for anon shared mem

[Eugene Batalov]

From: Fyodor <bocharovfedor at gmail.com>

If we want to use pagemap cache to obtain info about anon shared mem pages
dirtiness we should choose longest from private and shared vmas and then
create cache of this size. To simplify code we can do that while parsing
proc/smaps.
