Konstantin Belousov b59ea73029 Allow vinvalbuf() to operate with the shared vnode lock.
This mode allows other clean buffers to arrive while we flush the buf
lists for the vnode, which is fine for the targeted use.  We only need
that all buffers existed at the time of the function start were
flushed.  In fact, only one assert has to be relaxed.
