Revert "KVM: x86: check for cr3 validity in ioctl_set_sregs"
(cherry picked from commit dc7e795e3dd2a763e5ceaa1615f307e808cf3932)
This reverts commit 6c20e1442bb1c62914bb85b7f4a38973d2a423ba.
To my understanding, it became obsolete with the advent of the more
robust check in mmu_alloc_roots (89da4ff17f). Moreover, it prevents
the conceptually safe pattern
1. set sregs
2. register mem-slots
3. run vcpu
by setting a sticky triple fault during step 1.
