KVM: Silence underflow warning in avic_get_physical_id_entry()
Smatch complains that we check cap the upper bound of "index" but don't check for negatives. It's a false positive because "index" is never negative. But it's also simple enough to make it unsigned which makes the code easier to audit. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Radim Krčmář <rkrcmar@redhat.com>
