[PATCH] doc: remove multi-queue reconnection known issue

[xuan.ding@intel.com]

From: Xuan Ding <xuan.ding@intel.com>

Since QEMU 5.2.0 fixes the vhost multi-queue reconnection issue
in commit f66337bdbfda ("vhost-user: save features of multiqueues
if chardev is closed"), this patch removes the previous description
from known issue.

-Vhost multi-queue reconnection failed with QEMU version >= 4.2.0
-----------------------------------------------------------------
-
-**Description**
-   It's a QEMU regression bug (bad commit: c6beefd674ff). QEMU only saves
-   acked features for one vhost-net when vhost quits. When vhost reconnects
-   to virtio-net/virtio-pmd in multi-queue situations, the features been
-   set multiple times are not consistent.
-
-**Implication**
-   Vhost cannot reconnect back to virtio-net/virtio-pmd normally.
-
-**Resolution/Workaround**:
-   It is possible to filter the incorrect acked features at vhost-user side.
-
-**Affected Environment/Platform**:
-   ALL.
-
-**Driver/Module**:
-   Virtual Device Poll Mode Driver (PMD).
