rG303d3ae7e841: ufs, msdosfs: do not record witness order when creating vnode
rGd51b0786a2f6: msdosfs_denode.c: some style

Summary

When allocating new vnode, we need to lock it exclusively before
making it externally visible.  Since other threads cannot observe the
vnode yet, current lock order cannot create LoR conditions.
