Li Zefan f5fc1ec5e8 kernfs: introduce kernfs_pin_sb() 
commit 4e26445faa upstream.

kernfs_pin_sb() tries to get a refcnt of the superblock.

This will be used by cgroupfs.

v2:
- make kernfs_pin_sb() return the superblock.
- drop kernfs_drop_sb().

tj: Updated the comment a bit.

[ This is a prerequisite for a bugfix. ]
