bfs: don't use WARNING: string when it's just info.

Make the printk() [bfs "printf" macro] seem less severe by changing
"WARNING:" to "NOTE:".

<asm-generic/bug.h> warns us about using WARNING or BUG in a format string
other than in WARN() or BUG() family macros.  bfs/inode.c is doing just
that in a normal printk() call, so change the "WARNING" string to be
"NOTE".
