Tim Chase 076821eaff Create a new thread during recursive taskq dispatch if necessary
When dynamic taskq is enabled and all threads for a taskq are occupied,
a recursive dispatch can cause a deadlock if calling thread depends on
the recursively-dispatched thread for its return condition.

This patch attempts to create a new thread for recursive dispatch when
none are available.
