Use taskq_wait_outstanding() function

Browse Source 
Replace taskq_wait() with taskq_wait_oustanding().  This way callers
will only block until previously submitted tasks have been completed.
This was the previous behavior of task_wait() prior to the introduction
of taskq_wait_outstanding() so this isn't really a functionalty change
for these callers.
