In  v_addpollinfo(), we allocate storage to back vp->v_pollinfo.  However,
we may sleep when doing so; check that we didn't race with another thread
allocating storage for the vnode after allocation is made to a local
pointer, and only update the vnode pointer if it's still NULL.  Otherwise,
accept that another thread got there first, and release the local storage.

Discussed with:	jmg
