[PATCH] ext4: fix transposition typo in format string

[Rasmus Villemoes <linux@rasmusvillemoes.dk>]

According to C99, %*.s means the same as %*.0s, in other words, print
as many spaces as the field width argument says and effectively ignore
the string argument. That is certainly not what was meant here. The
kernel's printf implementation, however, treats it as if the . was not
there, i.e. as %*s. I don't know if de->name is nul-terminated or not,
but in any case I'm guessing the intention was to use de->name_len as
precision instead of field width.

If de->name is not guaranteed to be nul-terminated, I suppose this is
even -stable material.
