FreeBSD: Remove BIO_ORDERED flag from BIO_FLUSH
ZFS always waits for the write completion before flushing the cache.
That is why it does not require explicit ordering fences around it,
which are pretty difficult to implement for NVMe, since one has no
internal concept of strict request ordering.
This was already removed from FreeBSD once, but got resurrected
by mistake during OpenZFS merge.
