KVM: VMX: Access @flags as a 32-bit value in __vmx_vcpu_run()
Access @flags using 32-bit operands when saving and testing @flags for
VMX_RUN_VMRESUME, as using 8-bit operands is unnecessarily fragile due
to relying on VMX_RUN_VMRESUME being in bits 0-7. The behavior of
treating @flags a single byte is a holdover from when the param was
"bool launched", i.e. is not deliberate.
