[JFFS2] Quiet lockdep false positive.
Don't hold f->sem while calling into jffs2_do_create(). It makes lockdep unhappy, and we don't really need it -- the _reason_ it's a false positive is because nobody else can see this inode yet and so nobody will be trying to lock it anyway. Signed-off-by: David Woodhouse <dwmw2@infradead.org>
