x86/cpu/vmware: Use the full form of INL in VMWARE_HYPERCALL, for clang/llvm
LLVM's assembler doesn't accept the short form INL instruction:
inl (%%dx)
but instead insists on the output register to be explicitly specified.
This was previously fixed for the VMWARE_PORT macro. Fix it also for
the VMWARE_HYPERCALL macro.
