This patch should resolve the bugs reported by the sparse tool.
Initial reports were written by "kbuild test robot" managed by fengguang.wu.
In my local machines, I've tested also by running:
> make C=2 CF="-D__CHECK_ENDIAN__"
Accordingly, I've found lots of warnings and bugs related to the endian
conversion. And I've fixed all at this moment.

This adds address space operations for data.
- F2FS supports readpages(), writepages(), and direct_IO().
- Because of out-of-place writes, f2fs_direct_IO() does not write data in place.
