Fix cpu hotplug atomic sleep issue
We move the spinlock unlock before the thread creation. This should be
safe because the thread creation code doesn't actually manipulate any
taskq data structures; that's done by the thread once it's created.

We also remove the assertion that the maxthreads is the current threads
plus one; that assertion could fail if multiple hotplug events come in
quick succession, and the first new taskq thread hasn't had a chance to
start processing yet.
