Yann E. MORIN a67f4c3e29 fs/ext2: hint about setting the filesystem size on error
Since we now request that the user sets the exact size of the ext2/3/4
filesystem, we've had quite a few users wondering what was going on when
they enable too much and the default 60M are no longer enough.

When mkfs.ext2 fails, print a hint that the user should check the size
setting.
