inode numbering: change libfs sb creation routines to avoid collisions with their root inodes
This patch makes it so that simple_fill_super and get_sb_pseudo assign their root inodes to be number 1. It also fixes up a couple of callers of simple_fill_super that were passing in files arrays that had an index at number 1, and adds a warning for any caller that sends in such an array. It would have been nice to have made it so that it wasn't possible to make such a collision, but some callers need to be able to control what inode number their entries get, so I think this is the best that can be done.
