In tagq_free(), fix the test checking whether a TAGQ should be removed from
its tailq. This required introducing a new flag in the TAGQ structure to
avoid reverting to poking under the hood of the queue.h API.
The concrete bug it solves is that using tags would make vi crash reliably
on exit.
missed setting TAG_IS_LINKED in a special case in my previous commit.
Bug reported by Brad Harder, thanks!
