[f2fs-dev][PATCH 2/2 v2] f2fs: invalidate xattr node page when evict inode

[Chao Yu]

When inode is evicted, all the page cache belong to this inode should be
released including the xattr node page. But previously we didn't do this, this
patch fixed this issue.

v2:
 o reposition invalidate_mapping_pages() to the right place suggested by
Jaegeuk Kim.
