[PATCH] v9fs: fix corner cases when flushing request
When v9fs_mux_rpc sends a 9P message, it may be put in the queue of unsent
request. If the user process receives a signal, v9fs_mux_rpc sets the
request error to ERREQFLUSH and assigns NULL to request's send message. If
the message was still in the unsent queue, v9fs_write_work would produce an
oops while processing it.
The patch makes sure that requests that are being flushed are moved to the
pending requests queue safely.
If a request is being flushed, don't remove it from the list of pending
requests even if it receives a reply before the flush is acknoledged. The
request will be removed during from the Rflush handler (v9fs_mux_flush_cb).
