FreeBSD: Implement taskq_init_ent()

Browse Source 
Previously taskq_init_ent() was an empty macro, while actual init
was done by taskq_dispatch_ent().  It could be slightly faster in
case taskq never enqueued. But without it taskq_empty_ent() relied
on the structure being zeroed by somebody else, that is not good.

As a side effect this allows the same task to be queued several
times, that is normal on FreeBSD, that may or may not get useful
here also one day.
