iget: stop EXT2 from using iget() and read_inode()
Stop the EXT2 filesystem from using iget() and read_inode(). Replace
ext2_read_inode() with ext2_iget(), and call that instead of iget().
ext2_iget() then uses iget_locked() directly and returns a proper error code
instead of an inode in the event of an error.
ext2_fill_super() returns any error incurred when getting the root inode
instead of EINVAL.
