virtiofs: No need to check fpq->connected state

task #28910367
commit 7ee1e2e631dbf0ff0df2a67a1e01ba3c1dce7a46 upstream

In virtiofs we keep per queue connected state in virtio_fs_vq->connected
and use that to end request if queue is not connected. And virtiofs does
not even touch fpq->connected state.

We probably need to merge these two at some point of time. For now,
simplify the code a bit and do not worry about checking state of
fpq->connected.
