UBUNTU: Drop ndiswrapper

UBUNTU: Drop ndiswrapper

ndiswrapper is now supported via a DKMS package:

https://launchpad.net/ubuntu/+source/ndiswrapper

It is therefore unnecessary to duplicate effort and support this as a
separate out of tree driver in the kernel.  ndiswrapper was already
disabled in the Makefile so there should be no affects from dropping the
code.

I'm adding this commit commentary so that there is a paper trail for why
this was removed from the kernel.  After the next upload, all evidence
of ndiswrapper will be rebased out of existence.
