[PATCH] squashfs: fix inode number description in documentation

[Ray Lee]

The documentation incorrectly described the inode identifier as a
48-bit number.  In reality it is a 64-bit integer where the upper 48
bits hold the location of the compressed metadata block and the lower
16 bits hold the byte offset into the uncompressed block.

 Inodes are packed into the metadata blocks, and are not aligned to block
 boundaries, therefore inodes overlap compressed blocks.  Inodes are identified

 To maximise compression there are different inodes for each file type
