Jason Wang 5e6b394621 vhost_net: validate sock before trying to put its fd 
[ Upstream commit b8f1f65882f07913157c44673af7ec0b308d03eb ]

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.
