Subject: [PATCH 5.6 001/194] KVM: nVMX: Consolidate nested MTF checks to helper function

From: Oliver Upton <oupton@...gle.com>

[ Upstream commit 212617dbb6bac2a21dec6ef7d6012d96bb6dbb5d ]

commit 5ef8acbdd687 ("KVM: nVMX: Emulate MTF when performing
instruction emulation") introduced a helper to check the MTF
VM-execution control in vmcs12. Change pre-existing check in
nested_vmx_exit_reflected() to instead use the helper.
