[PATCH] f2fs: fix to record dirty page count for symlink

[Chao Yu <chao2.yu@samsung.com>]

Dirty page can be exist in mapping of newly created symlink, but previously
we did not maintain the counting of dirty page for symlink like we maintained
for regular/directory, so the counting we lookuped should be wrong.

This patch adds missed dirty page counting for symlink to fix this issue.
