[Qemu-devel] [PATCH v4 15/17] thread-pool: drop thread_pool_active()

[Stefan Hajnoczi <stefanha@redhat.com>]

.io_flush() is no longer called so drop thread_pool_active().  The block
layer is the only thread-pool.c user and it already tracks in-flight
requests, therefore we do not need thread_pool_active().
