This is a breaking change of a UAPI though the new semantics looks cleaner and VMMs are not prepared for this. Firecracker, QEMU, and crosvm perform migration by listing registers with KVM_GET_REG_LIST, getting their values with KVM_GET_ONE_REG and setting them with KVM_SET_ONE_REG. This algorithm assumes KVM_SET_ONE_REG restores the values retrieved with KVM_GET_ONE_REG without any alteration. However, bit operations added by the earlier commit do not preserve the values retried with KVM_GET_ONE_REG and potentially break migration. Remove the bit operations that alter the values retrieved with KVM_GET_ONE_REG.
