vhost: fix missing guest pages table NUMA realloc
[ upstream commit 57589cdfd784e6704ded490d80038584d6ade9df ]
When the guest allocates virtqueues on a different NUMA node
than the one the Vhost metadata are allocated, both the Vhost
device struct and the virtqueues struct are reallocated.
However, reallocating the guest pages table was missing, which
likely causes at least one cross-NUMA accesses for every burst
of packets.
This patch reallocates this table on the same NUMA node as the
other metadata.
Fixes: e246896178e6 ("vhost: get guest/host physical address mappings")
