fuse: cleanup request queuing towards virtiofs

Virtiofs has its own queuing mechanism, but still requests are first queued
on fiq->pending to be immediately dequeued and queued onto the virtio
queue.

The queuing on fiq->pending is unnecessary and might even have some
performance impact due to being a contention point.

Forget requests are handled similarly.

Move the queuing of requests and forgets into the fiq->ops->*.
fuse_iqueue_ops are renamed to reflect the new semantics.
