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.
Fixes: b37e95507e1b ("doc: add vhost multi-queue reconnection 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).
