KVM: SVM: Fix wrong intercept masks on 32 bit
commit 061e2fd16863009c8005b4b5fdfb75c7215c0b99 upstream.
This patch makes KVM on 32 bit SVM working again by
correcting the masks used for iret interception. With the
wrong masks the upper 32 bits of the intercepts are masked
out which leaves vmrun unintercepted. This is not legal on
svm and the vmrun fails.
Bug was introduced by commits 95ba827313 and 3cfc3092.
