Junjie Mao 1a1ee93656 HV: hypercall: make hypercall functions return int32_t
The error code in the hypervisor is 32-bit signed integers. To reduce implicit
conversions, this patch make hcall_xxx returns int32_t, and finally converts it
to uint64_t when assigned to rax whose semantics is properly defined in C99.
