This series fixes couple of unittest failures for SVM.
1.The test ./x86/access is failing with timeout.
2.The test ./x86/svm failure with infinite loop.

v2:
1. Modified the check in ac_test_legal to limit the number of test
combinations based on comments from Paolo Bonzini and Sean Christopherson.
2. Changed the rdrand function's retry method. Kept the retry outside the
function. Tom Lendacky commented that RDRAND instruction can sometimes
loop forever without setting the carry flag.

Applied, thanks. I'm looking at a few more limits to the number of
tests as well as optimizations to ac_emulate_access, which should reduce
the runtime further.
