Merge pull request #168 from giuseppe/drop-O_DIRECT 
main: reset O_DIRECT on open

main: reset O_DIRECT on open 
having the fd open with O_DIRECT causes pwrite64 to fail with EINVAL
if the write buffer is not aligned.  Since we have no control on the
buffer provided by libfuse, just drop O_DIRECT.

Fix possible segmentation fault in direct_fsync() 
If the call to `get_upper_layer(lo)` returns `NULL` then the
`node->layer` will be `NULL`, too. If this is the case we pass `NULL` to
`direct_fsync()` which will cause a segmentation fault in:

```c
cfd = openat(l->fd, path, O_NOFOLLOW|O_DIRECTORY);
```

To fix this we now apply an additional check and error in the case of
`get_upper_layer(lo) == NULL`.
