Potential fix for panic during shutdown.

When a tty is revoked, the opencount of its associated vnode is forced to
zero and calling vop_stdclose() on this vnode causes a panic.  Call therefore
vop_stdclose() from spec_close() if and only if the opencount is strictly
positive.

I haven't managed to reproduce the original panic locally, hence the
"potential" above.
