[PATCH] fuse: check O_DIRECT

Check O_DIRECT and return -EINVAL error in open.  dentry_open() also checks
this but only after the open method is called.  This patch optimizes away
the unnecessary upcalls in this case.

It could be a correctness issue too: if filesystem has open() with side
effect, then it should fail before doing the open, not after.
