KVM: VMX: Read 32-bit GPR values for ENCLS instructions outside of 64-bit mode
When getting register values for ENCLS emulation, use kvm_register_read()
instead of kvm_<reg>_read() so that bits 63:32 of the register are dropped
if the guest is in 32-bit mode.
Note, the misleading/surprising behavior of kvm_<reg>_read() being "raw"
variants under the hood will be addressed once all non-benign bugs are
fixed.

Fixes: b6f084ca5538 ("KVM: VMX: Add ENCLS[EINIT] handler to support SGX Launch Control (LC)")
