vmx: vmxnet3_load_mbuf will still do the wrong thing

[Mike Belopuhov]

Hi,

We've just run into a vmx panic and code inspection revealed
that my previous diff contained a mistake, the pullup operation
is called on a wrong mbuf chain.

I apologize for overlooking this issue.

We're not 100% certain that this fixes our exact problem yet
since we can't reproduce it at will, but the diff appears
correct to us.  Please test and report any problems.

Thanks!
