Chunwei Chen da8f51e16a Use a dedicated taskq for vdev_file

The introduction of parallel zvol prefetch causes deadlock when using
vdev_file.

spa_async->(spa_namespace_lock)->txg_wait_synced->(wait for txg_sync)
txg_sync->zio_wait->(wait for vdev_file_io_fsync on system_taskq)
zvol_prefetch_minors_impl (on system_taskq)->spa_open_common->(wait for spa_namespace_lock)

We fix this by using dedicated taskq for vdev_file.  This same change
was originally made in commit bc25c93 but reverted in commit aa9af22
when dynamic taskqs were added.
