annotate: always adjust linkrev before walking down to parents (issue4623)
This should avoid the bad performance in the following scenario. Before this
patch, on "hg annotate -r10000", p.rev() would walk changelog from 10000 to 3
because _descendantrev was 10000. With this patch, it walks from 5 to 3.
1 -- 2 -- 4 -- 5 -- ... -- 10000
\ 'p' 'f'
- 3 (grafted 3 to 4)
'p'

This patch involves extra calls of narrow _adjustlinkrev(), but the cost of
them seems relatively small compared to wide _adjustlinkrev() calls eliminated
by this patch.
