Jason Wang b8f1f65882 vhost_net: validate sock before trying to put its fd
Sock will be NULL if we pass -1 to vhost_net_set_backend(), but when
we meet errors during ubuf allocation, the code does not check for
NULL before calling sockfd_put(), this will lead NULL
dereferencing. Fixing by checking sock pointer before.

Fixes: bab632d69e ("vhost: vhost TX zero-copy support")
