lfs_fs_forceconsistency may not run upon file creation

[amgross]

Hi @geky ,
From what I see in code, lfs_fs_forceconsistency always run before operation that change the disk.
The only exception is when open is called on non-existing file with LFS_O_CREAT flag but without LFS_O_WRONLY (for example, if someone wants to create empty file).
Is it in purpose? (or bug that can corrupt the filesystem after powerdown...?)
Another interesting point is that attributes won't be written to file in this case, even after closing.

Didn't checked it, but probably same issue with LFS_O_TRUNC without LFS_O_WRONLY.
