[PATCH] 2TB files: change type of kstatfs entries

This fix was proposed by Trond Myklebust.  He says: The type "sector_t" is
heavily tied in to the block layer interface as an offset/handle to a block,
and is subject to a supposedly block-specific configuration option:
CONFIG_LBD.  Despite this, it is used in struct kstatfs to save a couple of
bytes on the stack whenever we call the filesystems' ->statfs().

So kstatfs's entries related to blocks are invalid on statfs64 for a network
filesystem which has more than 2^32-1 blocks when CONFIG_LBD is disabled.

- struct kstatfs
  Change the type of following entries from sector_t to u64.
  f_blocks
  f_bfree
  f_bavail
  f_files
  f_ffree
