Subject: [PATCH] [f2fs-dev] f2fs: use f2fs_get_node_page when write inline
 data

Subject: [PATCH] [f2fs-dev] f2fs: use f2fs_get_node_page when write inline data

We just need inode page when write inline data, use
f2fs_get_node_page() to get it instead of using dnode_of_data,
which can eliminate unnecessary struct use.
