Yonghua Huang 9b37e1464c add IO requrest 'req_buf' check before reference 
This address maybe invalid if a hostile address was set
in hypercall 'HC_SET_IOREQ_BUFFER'.it should be validated
before using.

Update:
  -- save HVA to guest OS's request buffer in hyperviosr
  -- change type of 'req_buf' from 'uint64_t' to 'void *'
  -- remove HPA to HVA translation code when using this addr.
  -- use error number instead of -1 when return error cases.
