[PATCH] vhost: Remove the unused variable.

[PATCH] vhost: Remove the unused variable.

[Tonghao Zhang]

The patch (7235acdb1) changed the way of the work
flushing in which the queued seq, done seq, and the
flushing are not used anymore. Then remove them now.

Fixes: 7235acdb1 ("vhost: simplify work flushing")
