NTFS: Continuing sparse annotations: finish data types and header files. 

- Add leMFT_REF data type to fs/ntfs/layout.h.
- Update all NTFS header files with the new little endian data types.
  Affected files are fs/ntfs/layout.h, logfile.h, and time.h.
- Do proper type casting when using ntfs_is_*_recordp() in
  fs/ntfs/logfile.c, mft.c, and super.c.

* The Update Sequence Array (usa) is an array of the le16 values which belong
* to the end of each sector protected by the update sequence record in which
* this array is contained. Note that the first entry is the Update Sequence
* Number (usn), a cyclic counter of how many times the protected record has
* been written to disk. The values 0 and -1 (ie. 0xffff) are not used. All
* last u16's of each sector have to be equal to the usn (during reading) or
* last le16's of each sector have to be equal to the usn (during reading) or
* are set to it (during writing). If they are not, an incomplete multi sector
* transfer has occurred when the data was written.
* The maximum size for the update sequence array is fixed to:
* maximum size = usa_ofs + (usa_count * 2) = 510 bytes
* The 510 bytes comes from the fact that the last u16 in the array has to
* (obviously) finish before the last u16 of the first 512-byte sector.
* The 510 bytes comes from the fact that the last le16 in the array has to
* (obviously) finish before the last le16 of the first 512-byte sector.

* (usa_count * 2) has to be less than or equal to 510.
