[PATCH] remove overwrite_paravirt_ops

[chrisw at sous-sol.org (Chris Wright)]

It's not used, and we can be explicit in a paravirt_ops about which native
pieces are preferred, so it's not needed.  Also, the loop is a bit dodgy
(works ok, since sizeof(unsigned int) is 4 on x86, but...)  Before I
commit, any objections?
