Add a simple test for SMM, based on VMX. The test implements its own
sync between the guest and the host as using our ucall library seems to
be too cumbersome: SMI handler is happening in real-address mode.
This patch also fixes KVM_SET_NESTED_STATE to happen after
KVM_SET_VCPU_EVENTS, in fact it places it last. This is because
KVM needs to know whether the processor is in SMM or not.

Starting state migration after an IO exit without first completing IO
may result in test failures. We already have two tests that need this
(this patch in fact fixes evmcs_test, similar to what was fixed for
state_test in commit 0f73bbc851, "KVM: selftests: complete IO before
migrating guest state", 2019-03-13) and a third is coming. So, move the
code to vcpu_save_state, and while at it do not access register state
until after I/O is complete.

Pull libnvdimm fixes from Dan Williams:
"I debated holding this back for the v5.2 merge window due to the size
of the "zero-key" changes, but affected users would benefit from
having the fixes sooner. It did not make sense to change the zero-key
semantic in isolation for the "secure-erase" command, but instead
include it for all security commands.
The short background on the need for these changes is that some NVDIMM
platforms enable security with a default zero-key rather than let the
OS specify the initial key. This makes the security enabling that
landed in v5.0 unusable for some users.
Summary:
- Compatibility fix for nvdimm-security implementations with a
default zero-key.
- Miscellaneous small fixes for out-of-bound accesses, cleanup after
initialization failures, and missing debug messages"
