We can directly return '0' from the function, instead of introducing a
'ret' variable.

The recovery routine should do all the time regardless of normal umount action.

In f2fs_statfs(), f_files should be the total number of available inodes
instead of the currently allocated inodes.
So, this patch should resolve the reported bug below.
Note that, showing 10% usage is not a bug, since f2fs reveals whole volume size
as much as possible and shows the space overhead as *used*.
This policy is fair enough with respect to other file systems.
<Reported Bug>
(loop0 is backed by 1GiB file)
$ mkfs.f2fs /dev/loop0
F2FS-tools: Ver: 1.1.0 (2012-12-11)
Info: sector size = 512
Info: total sectors = 2097152 (in 512bytes)
Info: zone aligned segment0 blkaddr: 512
Info: format successful
$ mount /dev/loop0 mnt/
$ df mnt/
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/loop0 1046528 98312 929784 10%

$ df mnt/ -i
Filesystem Inodes IUsed IFree IUse% Mounted on
/dev/loop0 1 -465918 465919 - /home/zeta/linux-devel/mtd-bench/mnt
Notice IUsed is negative. Also, 10% usage on a fresh f2fs seems too
much to be correct.

Since, __GFP_ZERO is used while f2fs inode allocation, so we do not
need memset for f2fs_inode_info, as this is already zeroed out.

As pointed out by Randy Dunlap, this patch removes all usage of "/**" for comment
blocks. Instead, just use "/*".

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 the implementation of superblock operations for f2fs, which includes
- init_f2fs_fs/exit_f2fs_fs
- f2fs_mount
- super_operations of f2fs
