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